Power BI Service | Dataflows throwing Internal Service Errors upon Refresh

[Mvanruys]

Hey all

Since yesterday afternoon (3 pm CET), I noticed that the dataflows we use within our organization are all throwing an internal service error (DataflowInternalError) upon refresh or upon connection to one of them in Power BI Desktop. This is the message I got in my inbox from one of the failed scheduled refreshes:

"Your dataflow couldn’t be refreshed because there was a problem with one or more entities, or because dataflow capabilities were unavailable.
The next refresh is scheduled for August 13, 2020 10:30 UTC."

At first I thought it was unique to one Dataflow but all of are flows seem to be impacted by this issue. The dataflows are based on table views from Oracle and SQL databases, connecting to the database directly works in Power BI Desktop, Toad, SQLDev so it doesn't seem like the issue is on the database's end at first glance.

Not sure if anyone is experiencing (or has experienced) the same and knows a workaround or a fix?

Thanks

Mathias

This issue must from the datasource of one of the entities in the dataflow. I would recommend you to create a support ticket for troubleshooting.
