bad_request

The request could not be read. Guv could not read the request at all, usually because the body is not valid JSON or the content type is missing.

• HTTP status: 400 Bad Request
• 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 a valid JSON body with Content-Type: application/json.

Common causes

• A trailing comma or unquoted key in the JSON body.
• Sending form data or plain text without Content-Type: application/json.

What the response looks like

{
  "type": "https://guv.dev/errors/bad_request",
  "title": "The request could not be read",
  "status": 400,
  "code": "bad_request",
  "detail": "Guv could not read the request at all, usually because the body is not valid JSON or the content type is missing.",
  "fix": "Send a valid JSON body with Content-Type: application/json.",
  "docs_url": "https://guv.dev/errors/bad_request",
  "request_id": "req_01jbx2m9k7q4r8t5v6w3y0z1rq"
}

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