unsupported_media_type

HTTP status: 415 Unsupported Media Type. Retrying the same request unchanged fails the same way.

Why it happens

• Content-Type isn't application/json, or names a charset other than UTF-8.
• The body is compressed (a Content-Encoding header).

What to do

Send uncompressed JSON with Content-Type: application/json.

Example

The response is application/problem+json. Branch on code, never on title or detail. See errors for the format.
