invalid_param

The invalid_param Problem means: a parameter is not of its type, misses its pattern, or is not one of its values.

Answer

Status	Title
400	Bad Request

JSON

{
  "type": "about:blank",
  "title": "Bad Request",
  "status": 400,
  "detail": "What went wrong, in words.",
  "code": "invalid_param"
}

Send the parameter as the operation declares it, as its docs page shows.
