API Returning HTTP Status Code 200 When It Should Return 429

[Keitsu42]

Recently the API has been returning JSON error messages with code 429 while the HTTP header is set as 200. The HTTP header should be set as 429 in this case as 200 indicates no error.

This is happening when I am trying to update orders using PATCH

Example of error from my log files:
22/06/19 07:53:13 | Error message received with HTTP status code: 200
22/06/19 07:53:13 | Requested address: /order/cb164cacd85a06c3c4a12b3f47513344
22/06/19 07:53:13 | Action type: PATCH
22/06/19 07:53:13 | code: 429
