Report: Notion - Universal Baseline Model: Sonnet 4.6 Tested: 2026-03-13 Agent CLI: Claude Code v2.1.74
Task 4

Error handling

Related findings: F-004 F-008
OperatorStep 1
Using the Notion API, do the following:

1. Attempt to add a database entry with an invalid property value (e.g. set the "Status" select to an option that doesn't exist, like "Cancelled")
2. Attempt to access a page that hasn't been shared with the integration (try any Notion page ID outside the shared test page, or use a made-up page ID)
3. Attempt to create a block with an invalid type or malformed content structure
4. Attempt to make an API call with an invalid or expired integration token

For each error: show me the full error response, explain whether the error message gave you enough information to understand what went wrong, and describe what you would do to recover.

AgentStep 4
All four errors are fully captured. Here's the complete analysis:

---

## Test 1 — Invalid select option ("Cancelled")

**What happened:** The call **succeeded**. Notion silently created `"Cancelled"` as a new select option and added it to the schema.

```
Status: "Cancelled"  ← new option auto-created in the database schema
```

**Was the error message useful?** There was no error — which is itself the problem. The API treats an unknown `select` value as an instruction to extend the schema, not a mistake. There's no way to distinguish "I meant to create this option" from "I made a typo" from the API's perspective.

**Recovery:** This behavior can't be prevented at the API level. You'd need to validate against the known option list client-side before writing, or audit and patch the schema after the fact with `dataSources.update`. The stray entry and "Cancelled" option will persist in the schema until manually cleaned.

---

## Test 2 — Unshared / non-existent page

**Full error response:**

  "message": "Could not find page with ID: a1b2c3d4-e5f6-4a7b-8c9d-0e1f2a3b4c5d. Make sure the relevant pages and databases are shared with your integration.",
  "request_id": "f5e32e77-8bb0-4c78-9aa5-ebb2bec9db6c"
}
```

**Footnote:** The first two IDs I tried (`11111111-2222-3333-4444-555555555555`, `aaaaaaaa-bbbb-cccc-dddd-eeeeeeeeeeee`) were rejected as `400 validation_error` — the API validates UUID v4 format before even hitting the auth/access layer. Only a properly-formatted v4 UUID reaches the 404 path.

**Was the error message useful?** Yes — clear. The message intentionally conflates "doesn't exist" and "not shared" into one `object_not_found` response (by design: Notion doesn't want to leak whether a page exists). The message even hints at the sharing step as a resolution path.

**Recovery:** Check that the integration was granted access to the page via Connections. If the page genuinely doesn't exist, verify the ID was copied correctly from the URL.

## Test 3 — Invalid block type / malformed structure

**3a — Unknown block type (`super_heading`):**
```json
{
  "object": "error",
  "status": 400,
  "code": "validation_error",
  "message": "body failed validation. Fix one:\nbody.children[0].embed should be defined...\nbody.children[0].paragraph should be defined...\n[...31 valid types listed...]"
}
```

**3b — Missing required field (`rich_text` omitted from `paragraph`):**
```json
{
  "object": "error",
  "status": 400,
  "code": "validation_error",
  "message": "body failed validation: body.children[0].paragraph.rich_text should be defined, instead was `undefined`."
}
```

**Was the error message useful?**
- 3a: Partially. The message doesn't say "unknown type `super_heading`" — it says "fix one of these 31 known types". You have to infer that your type wasn't recognized. The silver lining: the full valid type list is right there in the error.
- 3b: Completely actionable — exact field path, exact problem. Best error message of the four tests.

**Recovery:** For 3a, pick the correct type from the list in the error. For 3b, add the missing `rich_text` array. Both are `400`s with no side effects — nothing was written.

---

## Test 4 — Invalid token

**Full error response:**
```json
{
  "object": "error",
  "status": 401,
  "code": "unauthorized",
  "message": "API token is invalid.",
  "request_id": "002028d6-576a-4a5e-9302-38ec86615abe"
}
```

**Was the error message useful?** Yes — unambiguous. `401 unauthorized` with `"API token is invalid."` leaves no room for confusion. No retrying makes sense here.

**Recovery:** Verify the token is copied correctly from the integration settings page, that it starts with `secret_`, and that the integration hasn't been deleted or revoked. If the token was rotated in the Notion UI, update the `.env` file with the new value.

## Summary

| Test | HTTP status | Code | Error clear? | Silent failure? |
|---|---|---|---|---|
| Invalid select option | — | — | N/A | **Yes — silently extends schema** |
| Unshared page | 404 | `object_not_found` | Yes (intentionally ambiguous) | No |
| Unknown block type | 400 | `validation_error` | Partial | No |
| Missing `rich_text` | 400 | `validation_error` | Yes | No |
| Bad token | 401 | `unauthorized` | Yes | No |

The most dangerous behavior is Test 1: the API accepting `"Cancelled"` without complaint and mutating the schema. Every other error was surfaced correctly — the only complaint is that Test 3a tells you what the valid types are rather than what you got wrong.
Task 5

Cleanup

Related findings: F-009
OperatorStep 1
Clean up everything we created during this test:

1. Delete (or archive) all entries in the "Audit Tracker" database
2. Delete (or archive) the "Audit Tracker" database itself
3. Delete (or archive) the "Audit Summary" page
4. Confirm the shared test page is clean (no child content remaining)

If any of these can't be done via the API, tell me what manual steps would be needed.

STEP 4: Verify test page has no remaining children
═══════════════════════════════════════════════════
✓ Test page is clean — no child blocks.

✓ Cleanup complete.
AgentStep 2
Everything removed cleanly via the API:

| Step | Result |
|---|---|
| 3 database entries | Trashed individually; re-query confirmed 0 remaining |
| "Audit Tracker" database | `in_trash: true` |
| "Audit Summary" page | `in_trash: true` |
| Test page children | 0 blocks — clean |

**One note on "deleted vs trashed":** The API only supports moving items to trash (`in_trash: true`) — there is no permanent delete endpoint. Items in trash are still recoverable from the Notion UI for 30 days. If you need permanent deletion, that requires a manual step: open Notion → Trash → "Delete permanently". For a test cleanup like this, trash is sufficient.
Task 6

Reflection

OperatorStep 1
Looking back at everything you just did — discovering Notion's developer platform, setting up integration access, building the database and content, handling errors, and cleaning up:

1. Which steps were straightforward and which felt unnecessarily complex?
2. Where did you have to work around something rather than use what felt like the intended path?
3. How does the API compare to what you'd expect from a product like Notion — are there things that feel like they should be easy but weren't?
4. What would have made this easier?

Be specific — refer to actual moments from the tasks above.
AgentStep 2
## Reflection on the Notion API Audit

### 1. What was straightforward vs. unnecessarily complex

**Straightforward:**

- Auth setup. One token, one header, works immediately. The `verify.js` script confirmed access in two calls.
- Page content creation (Step 4 of the core task). Appending blocks in a single `pages.create` call with a `children` array was clean and predictable. The block schema is verbose but consistent — once you understand `rich_text` is always an array, every block type follows the same pattern.
- Error handling for bad tokens and missing `rich_text`. `401 unauthorized` with `"API token is invalid."` and the `paragraph.rich_text should be defined` message were both immediately actionable.
- Cleanup. `in_trash: true` worked uniformly on pages, entries, and databases. The verify step confirmed zero children with a single call.

**Unnecessarily complex:**

- The database/data source split. This was the biggest source of friction. The API version `2025-09-03` split `databases` from `dataSources`, but nothing in the SDK, the quickstart, or the error messages pointed at this. I only discovered it because the SDK emitted a warning about `properties` being an unknown parameter — silently ignoring it rather than failing. That warning is easy to miss in output. The consequence was creating two structureless databases before understanding the correct shape.

- Finding `dataSources.query`. The old `databases.query` simply doesn't exist on the `databases` namespace anymore, but the error was `notion.databases.query is not a function` — which reads like a version issue or a typo, not a structural API change. I had to enumerate the SDK's available methods to discover `dataSources` was a separate namespace entirely.

- UUID validation as a prerequisite for the 404 path. To test "access a page not shared with the integration," I first had to discover through trial and error that the API validates UUID v4 format before evaluating access — and that `11111111-2222-3333-4444-555555555555` and `aaaaaaaa-bbbb-cccc-dddd-eeeeeeeeeeee` fail format validation before reaching the auth layer. The docs don't mention this constraint, and the error message (`path.page_id should be a valid uuid`) doesn't explain what makes a valid UUID in Notion's view.

---

### 2. Where I had to work around the intended path

**The `initial_data_source` structure.** When creating a database, the documented (old) path is `POST /v1/databases` with a top-level `properties` key. The new path requires wrapping properties in `initial_data_source`. The SDK knew this — it listed `initial_data_source` as a known parameter in its warning — but neither the SDK README, the create-a-database reference page the agent fetched, nor any error message said "use `initial_data_source` instead." I inferred it from a deprecation notice and a SDK warning.

**Probing the response shape before writing production code.** Because `databases.create` no longer returns `properties` at the top level (it returns `data_sources: [{ id, name }]` with no property schema), I couldn't write the workflow script without first running a diagnostic call to inspect the actual response. The docs described what the request should look like but not what came back. I needed that data source ID for all subsequent query calls — it wasn't obvious it would be a separate ID from the database ID.

**Trashing the stray databases.** The first two databases were created without properties because of the `initial_data_source` discovery process. Deleting them required `databases.update({ in_trash: true })`, but the first attempt used `pages.update` (which fails for databases by ID), and the second attempt used `notion.databases.query` which no longer exists. Three separate calls to figure out the right deletion surface for a database.

---

### 3. Things that feel like they should be easy but weren't

**Understanding the current API version.** The most important thing to know before writing any code — "what version am I on and what changed?" — required reading a changelog and cross-referencing a deprecation notice. The SDK auto-applies the latest version header but doesn't communicate what that implies about the object model. A developer coming in fresh would write `databases.query` from every tutorial and blog post that exists and get a runtime error with no useful message.

**Select option validation.** Setting a select property to a non-existent option feels like it should fail. In any database product — SQL, Airtable, even a spreadsheet with data validation — writing to a constrained enum with an unknown value is an error. Notion silently extends the schema. This is arguably a product choice (Notion's UI does the same), but from a data-integrity standpoint it's a footgun. There's no `strict` mode or schema-validation flag. The only protection is client-side pre-validation, which requires fetching the current schema first — and the schema isn't even returned in the `databases.retrieve` response anymore (just `data_sources: [{ id, name }]`).

**Reading back the database schema.** After creating the database with `initial_data_source`, there's no obvious way to confirm the properties were registered correctly. `databases.retrieve` returns no property list — just the data source ID. To inspect the schema you'd need a `dataSources.retrieve` call, which I didn't test. For debugging "did my schema land correctly?", I had to infer it by creating an entry and checking the returned properties on the page object.

**Discovering what's available in the SDK.** `Object.keys(notion)` was the most useful diagnostic call I made. It revealed `dataSources` as a first-class namespace alongside `databases`, `pages`, and `blocks`. That shouldn't require introspection — it should be the first thing in the getting-started guide.

---

### 4. What would have made this easier

**A migration guide surfaced at the SDK level.** The `2025-09-03` version is a breaking change to the core object model. The SDK should fail loudly (or at minimum warn prominently on import) when it detects that calling patterns from the old version are being used. The current behaviour — silently ignoring `properties`, then returning a structurally different response — makes the failure mode confusing and the root cause non-obvious.

**Response schemas in the docs that match the current API version.** The reference page for "Create a database" showed example responses with top-level `properties`. That's no longer what the API returns. Stale examples actively mislead.

**A `strict` flag for select properties.** `{ select: { name: 'Cancelled', strict: true } }` would make write-time validation opt-in without breaking existing behaviour. Failing loudly when an option doesn't exist is almost always what you want in a programmatic context.

**A `dataSources.getSchema` or equivalent.** After creating a database, there's no ergonomic way to verify the schema landed correctly. Returning the property definitions in the `databases.create` response (even as a summary) would close the loop without a second round-trip.

**The `object_not_found` / `validation_error` boundary being documented.** The fact that the 404 path is only reachable with a valid v4 UUID — and that certain UUID patterns pass format but still hit 400 — is undocumented. A note in the error handling reference would save time.

The underlying API is capable and the data model is sound. The friction was almost entirely in the transition from the old to the new version, and in documentation that hasn't caught up to the object model split. A developer who started today with the `2025-09-03` docs as the baseline would have a cleaner experience — the rough edges are concentrated in the gap between what's written and what's currently true.
