Only non-success status codes are considered (greater or equal to 300). The retry codes are only considered for GET and POST requests. They take priority over the `dontRetryStatusCodes` option. By default, the tracker retries on all non-success status codes except for 400, 401, 403, 410, and 422. Signature: ```typescript retryStatusCodes?: number[]; ```
