These are the possible status codes:\r\n\r\n* 200 Conversion is successful. Response is a conversion result.\r\n* 202 Conversion in progress.\r\n* 404 JobId is invalid or response is expired.\r\n* 503 No concurrent poll requests are allowed..\r\n* 5XX Conversion error. Response is an error message.\r\n\r\nI mostly get 200 OK responses when polling after the confirmation, but there are cases where I get a 202 Accepted with blank content. I suppose I'm hitting the API too fast and there is some internal propagation still ongoing, but that is not the point anyway, I could simply retry it and it will work.\r\n\r\nThe problem is that, since the response content is a blank string, and since the get method uses the [handle_response method](https://github.com/ConvertAPI/convertapi-python/blob/392a48e637fa13f3aeb3a1f807b50f566b25c82f/convertapi/client.py#L44) to convert the response to JSON or raise an exception, I'm hitting the unexpected exception _json.decoder.JSONDecodeError_.\r\n\r\nThe other error responses would _raise_for_status_ and fail legitimely. The only problem is with the 202 response, that is a successful status (so it is not raised), but can't be returned as json. I wrote a small wrapper to solve this at my side:\r\n\r\n```python\r\ndef poll_retrieve(job_id):\r\n    convertapi.api_secret = settings.CONVERT_API_SECRET\r\n    response = requests.get(\r\n        convertapi.client.url(f\"job/{job_id}\"),\r\n        headers=convertapi.client.headers(),\r\n        timeout=convertapi.timeout or None,\r\n    )\r\n    response.raise_for_status()\r\n    if response.status_code == 202:\r\n        raise ConversionInProgressError\r\n    return response.json()\r\n```\r\n\r\nI could write a pull request, but I want to discuss with you the best approach first: is a new exception (like this ConversionInProgressError) a good idea? Or do you think returning a blank list would work better?","author":{"url":"https://github.com/michelts","@type":"Person","name":"michelts"},"datePublished":"2021-06-01T14:27:09.000Z","interactionStatistic":{"@type":"InteractionCounter","interactionType":"https://schema.org/CommentAction","userInteractionCount":3},"url":"https://github.com/21/convertapi-library-python/issues/21"}
