Khan3K opened a new pull request, #71456:
URL: https://github.com/apache/airflow/pull/71456
When a required field is missing from a REST API request, FastAPI/pydantic
currently returns the generic 422 message `"Field required"`, which does not
say *which* field is missing. This makes debugging requests against the Airflow
API needlessly slow, since users have to cross-reference the OpenAPI schema.
This PR registers a `RequestValidationErrorHandler` in the FastAPI error
handlers, so missing-field validation errors now name the offending field:
```json
{
"detail": [
{
"type": "missing",
"loc": ["body", "conn_type"],
"msg": "Field required: `conn_type` is a required field. Please
provide a value for it in the request.",
"input": {"connection_id": "my_conn"}
}
]
}
```
The response shape and all other validation errors are preserved exactly as
before; only the `msg` of `type == "missing"` errors is enhanced.
closes: #57721
