Data Flow Failed - Generic "There was a problem running this DataFlow " Message
I went in to edit the data flow and try to run preivew to and it says " Preview was unable to start. "
The source data updates every 15 minutes which triggers the dataflow to run, but for some reason even thought the source data updated the dataflow did not run for 3 runs it should have this morning and then once it did run it ran for 17 minutes (normally runs for ~40 seconds).
This has been a very reliable dataflow to this point and there have been no recent changes to the data flow or structure of the source data.
Any idea what is going on here? I cant even troubleshoot the issue in the dataflow due to preview not working.
