validation_failed

Request did not validate · HTTP 400

A field is missing, has the wrong type, is out of range, or is not one the route accepts — unknown fields are refused, not ignored. A cursor this API did not issue is refused the same way. detail names the field.

What to do: Fix the request; retrying it unchanged will fail the same way. Each route's fields and bounds are in the API reference.

Where it comes from:

• Control API

Branch on code; detail is for your logs and never for a user. All error codes.
