HTTP 415 Unsupported Media Type means the server cannot process the request body's media type (Content-Type). Common triggers: sending JSON with Content-Type: text/plain, sending form data to a JSON-only endpoint, or uploading an unsupported file format. The server should indicate which media types it accepts in the response body or Accept-Post/Accept-Patch headers.
Response includes the status code, standard headers (including Content-Type), and a small diagnostic JSON body describing the request and returned status.
