# Not supported

The API answered with HTTP 400 and the error code `not_supported`.

The operation does not apply to this item, for example a modification time on a folder.

Every error is an [RFC 9457](https://www.rfc-editor.org/rfc/rfc9457) problem document (`application/problem+json`). Match on `code`, never on the message text. See [errors](/docs/api/errors) for the full list.
