Update settings for a project by ID.

Patches the `settings` JSONB of the project identified by the path `project_id`. Only the
keys provided in the request body are changed; existing keys are kept.

**Settings**

- `tracing` (bool): enable/disable Langfuse tracing for this project. Off by default to
conserve the org's Langfuse rate-limit/credit budget. Gates tracing for both the
response path and evaluations; when off, evaluations fall back to cosine-only scoring.

**Scope:** superusers may patch any project across organizations. A project-scoped key may
patch only its own bound project; targeting any other `project_id` returns 403.

🌐 Web query:

For FastAPI 0.116.0, does a required Pydantic request-body parameter return HTTP 422 before the route handler runs when a PATCH request has no body?

💡 Result:

Yes, in FastAPI 0.116.0, if a route handler defines a required Pydantic request-body parameter, FastAPI will return an HTTP 422 Unprocessable Entity error before the route handler is executed if the request is missing a body [1][2][3]. FastAPI performs request validation—including parsing and validating the request body against the Pydantic model—as part of the request lifecycle before the handler function is called [3][4]. Because a Pydantic model parameter in a route signature is considered required by default, the framework expects a corresponding JSON payload [2][5][6]. If no body is provided, the validation layer detects the missing data and raises a RequestValidationError, which FastAPI automatically converts into an HTTP 422 response [1][2][4]. To avoid this 422 error when a body is optional, you must explicitly make the parameter optional in the route handler signature by assigning it a default value, typically None [2][5]: async def update_item(item: MyModel | None = None):... Note that while this allows the route handler to run without a body, the Pydantic model itself should generally have all fields set as optional (e.g., with = None) if the intention is to support partial updates via PATCH [7][1][2].

settings_in: ProjectSettingsUpdate is required, so FastAPI returns 422 before the handler runs. Make it optional, reject None, and add a test that calls client.patch(...) without json.

Document project-scoped access for the ID route.

PATCH /projects/{project_id}/settings is not superuser-only. A project-scoped key can also patch its bound project. State both authorization cases here so the wiki matches the route contract.
