Power BI dataflows internal error

[Jorenvdl]

Hello,

Since this morning I have 4 dataflows that give an Internal error all the time. I tried to open the dataflows and then it will show preview data. After saving it again it worked once, but at the next scheduled refresh the dataflows wouldn't refresh.

The dataflows have been working fine for the past few months and use most Sharepoint data sources.

Any suggestions?

Hi@Jorenvdl,

Please check if this link can help you, Dataflow Failed - Internal Error 

And if it doesn't work, can you provide more details, such as detailed error messages?

Hope it helps.

Best Regards,
