validation_failed

Returned as: The problem's code
HTTP status: 400 Bad Request
type: https://zautha.com/docs/errors/validation_failed

When it happens

The request was read, but one or more of its fields break a rule. The problem’s errors array has one entry per field: its field (the request’s field name, such as email_address or limit), a code from the field errors and a message.

{
  "type": "https://zautha.com/docs/errors/validation_failed",
  "title": "Bad Request",
  "status": 400,
  "detail": "One or more fields are invalid.",
  "code": "validation_failed",
  "errors": [{ "field": "limit", "code": "invalid_range", "message": "limit must be between 1 and 100." }],
  "trace_id": "…"
}

What to do

Fix each field the errors array names; branch on its code, not on the message. @zautha/js gives the same list as fieldErrors, with the field names in camelCase.
