HTTP status400 Bad Request
Codebad_request
Retry?No — fix the request and re-issue.

​
When this happens

The server received the request but could not process it. Typical causes:
  • The body is not valid JSON.
  • The Content-Type header is missing or wrong.
  • A required path parameter is malformed (e.g. a non-UUID where one is expected).
  • A schema constraint outside Pydantic’s type system was violated (e.g. mutually exclusive fields).
If the failure is a typed schema violation (missing fields, wrong type), the server returns validation_error (422) instead.

​
Example response

{
  "detail": "Request body is not valid JSON.",
  "code": "bad_request",
  "request_id": "5b3f6c7e-7d24-4d40-9b12-3a59c01c6e91",
  "doc_url": "https://docs.lasscyber.com/errors/bad_request"
}

​
How to fix

  1. Confirm the request body parses as JSON.
  2. Confirm Content-Type: application/json.
  3. Compare the body to the auto-generated schema in the API reference.
  4. If you are using an SDK, upgrade to the latest minor and re-run. Most bad_requests in the wild are misuse of low-level escape hatches.
