# Response Errors

> Error response JSON example:



```json
{
   "ResponseStatus": 
   {
      "ErrorCode": "400",
      "Message": "BadRequest",
      "Errors": 
      [
        {
            "ErrorCode": "1102",
            "FieldName": "PersonId",
            "Message": "Missing value"
        }
      ]
    }
}
```

If you try to access a non-existent endpoint, you will get a 404 error without a body.

In all other cases, error responses will be in the format shown here.

The first Error is the [HTTP Error](/guides/error-codes).

The second Error (nested in the Errors section) is the [C2Error](/guides/error-codes) which provides more details about why the request failed.
