I have a Dataflow that is scheduled to refresh twice a day. Over the weekend, it successfully refreshed a couple of times, but then started to fail. I do not get meaningful error messages. Instead, when I download the CSV file for the refresh, it says thing like "Error: Internal error Request ID: 1a74efbc-da2d-d0ef-707f-0efd86741928 Activity ID: 373515be-c301-4a3e-969e-d2b52145e3b0".
I have also received occassional timeout errors recently, which may or may not be related, since the most recent errors do not mention timeouts, but they started at around the same time.
If I edit the dataflow and try to preview the data, I do not seem to get any errors with the subset of data that the system ingests under such conditions.
Is there any way for me to obtain any more meaningful logs for debugging purposes?
