This error was caused by getting an unexpected answer from the server. I’ve tried 2-3 times and could not reproduce the error. Nevertheless, I’ve pushed a fix to retry a request a few times if it fails for any reason (previously, it was only retried if the request failed, not when the response content was invalid).
