The new error should follow this format:
HTTP status code: 400
"code": invalid-key
"message": "Invalid key '{key}' in '{json_pointer_to_parent}'"
"context: { "path": "{json_pointer_to_parent}", "key": "{key}" }Note:
1- remember to check if the OAS needs updating as well.
2- This error has been replaced with invalid-value (T369063)
