406 Not Acceptable

not_acceptable — Not acceptable

Message “The request could not be completed.”

What causes it

  • The `Accept` header is not a valid media type (for example `Accept: json`, with no slash) or names a format the API does not serve. This comes from the framework with no `details`.

How to fix it

  1. Send `Accept: application/json`, or omit the `Accept` header — every operation answers JSON by default.
  2. For batch exports, choose the format with the path extension (`.csv` / `.zip`) rather than `Accept`; see `unsupported_format`.

Operations that return it

Any operation can return this code.

See the API reference for the full list of operations.
