API error type

Validation Failed

HTTP 400 · https://errors.driftstack.dev/validation-failed

What it means

The request body parsed but failed schema validation — a field has the wrong type, an unknown key was sent, or a constraint (length, enum, format) was violated.

How to fix it

The `detail` field carries the validator output naming each offending field. Align the request with the documented schema and retry.

Where it appears

In the type field of the RFC 9457 application/problem+json error body, alongside title, status, detail, and an instance correlation id.
