Common causes
- The body isn’t a JSON object or a form the endpoint reads.
- A field is missing, misspelled, of the wrong type, or out of range.
- A query parameter or header isn’t one the endpoint takes.
What to do
Fix each fielderrors names (its pointer locates it in the body), then send the request again.
Example
REQ_001, REQ_002, REQ_003, REQ_004, REQ_005, SCHEMA_001, INVALID_REQUEST.
