We encountered an unexpected error - Power BI Service Dataflow
Dear Support team, I am getting following error while opening or editing Dataflow. "We encountered an unexpected error". Is this a know issue and any workaround? Regards Raj
This has noithing to do with too long exception. This is no exception. Just a Session ID and the above error message.
Look at the comment section of your Blog. Another user also reported about August Gateway update causing this error:
https://powerbi.microsoft.com/en-us/blog/on-premises-data-gateway-august-2021-update-is-now-available/
Did you update your Gateway to the latest (Aug 2021) release by any chance?
We are seeing this error since this morning and only thing we updated was the Onprem Gateway.
I am able to open and edit Dataflows that does not use a Gateway.
Also tested a Dataflow that uses an Older version of Gateway, and that works fine!
