A task was canceled

ebjim — Mon, 08 Jan 2024 14:24:22 GMT

Starting 2 days ago, this error has been appearing when I refresh a dataflow that was previously working fine. As it is, the DF is a pretty simple one, soI tried removing quries and toggling the staging option because that's all I can do. But nothing helped. Anyone else experiencing some unexplainable error lately?

Hi ebjim
Thanks for using Fabric Community.
This might be an intermittent issue. Can you please try this after a day and let us know if the issue still persists?
You can also follow these troubleshooting steps:

Check Gateway: If using a gateway, ensure it's online, up-to-date, and configured correctly for all data sources and destinations.
Examine Capacity: If working in a shared capacity, confirm sufficient resources are available. Monitor capacity metrics for memory or CPU constraints.

Hope this helps. Please let me know if you have any further issues.

No gateway is in use. Additionally, I have 64 CUs and only one DF refreshing at any given time. I have also received another similar error:

999999 Couldn't refresh the entity because of an issue with the mashup document MashupException.Error: We're sorry, an error occurred during evaluation.

I found a solution: add a filter rows step on some queries in the DF. Because this was previously not needed, I wonder if available backend resources has been reduced or unseen changes made to how datasets (>1 million rows) are processed.
