A task was canceled

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?

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.

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. 

Hi @ebjim 
Thanks for the information. This error seems to be a bug or an undefined situation.

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.
