unsupported_media_type

Unsupported Content-Type. The Content-Type of the request is not one this endpoint accepts.

• HTTP status: 415 Unsupported Media Type
• CLI exit code: 2 (the request or file is not valid)
• Retry: not as it is; the same request will fail the same way until the cause is fixed

How to fix it

Send Content-Type: application/json.

What the response looks like

{
  "type": "https://guv.dev/errors/unsupported_media_type",
  "title": "Unsupported Content-Type",
  "status": 415,
  "code": "unsupported_media_type",
  "detail": "The `Content-Type` of the request is not one this endpoint accepts.",
  "fix": "Send Content-Type: application/json.",
  "docs_url": "https://guv.dev/errors/unsupported_media_type",
  "request_id": "req_01jbx2m9k7q4r8t5v6w3y0z1rq"
}

The code field is stable: match on it, not on title or detail, which may be reworded.
