Today, I've had a usually successful flow fail for me 3x in a row. I haven't made any changes to the flow; it just started failing. It runs for roughly 80 minutes, and ultimately shows the expected Rows Generated count while it is running. However, before it finishes, it suddenly fails on output. These are the failure messages I've seen:
1) System error: 404 NOT_FOUND An internal error occurred. Contact your administrator.
2) System error: 404 NOT_FOUND An internal error occurred. Contact your administrator.
3) System error: Unexpected end of file from server An internal error occurred. Contact your administrator.
Other flows have been working, but not this one. Since we're on Tableau Cloud, I also checked our site space usage, and we should have enough storage space.
What could be happening here?
UPDATE: The flow started working again the following day, with absolutely no changes made by me. This must have been a Tableau Cloud issue that was resolved. I have not experienced an error on the flow since.
