> The request body is invalid.

Source: https://tickwire.io/docs/errors/invalid_request/

HTTP 400.

**Likely cause:** Not a JSON object, or a field fails validation.

**What to do:** Fix the body; the message names the field.

**Retry:** No. The same request gets the same answer; change something first.
