Resubmit a job with only one request, still encountering the same issue: the logs show multiple same requests, and cost me $20 (the same request I ran without batch mode is ~$2).
This time I let it run over, and after 10 hours, it failed with following empty error information…
{“id”: “batch_req_695f7ab53af081909f8093a3d1b36e74”, “custom_id”: “124904021”, “response”: {“status_code”: 0, “request_id”: “”, “body”: {}}, “error”: null}
I am pretty sure this is a similar issue as this previous post Batch api Task runs repeatedly
