Dataflow refresh "Error: An internal error occurred"(Sharepoint Source)

[DCabaud]

Hello, 

I just created a dataflow with the webapp PowerBI, in the request editor I didn't have any problem to load a preview of my data and to apply transformations. But when I save my dataflow and try to refresh it I have an error:   

Invalid date,BP_2016_2017,Echec,MainByPage,04/11/2019 16:34:48,04/11/2019 16:34:51,Echec,Error: An internal error occurred... RootActivityId = 6b398f25-7f6c-4695-8f64-2686ab6e0a5b.Param1 = Information about a data source is required. Request ID: 3805aae8-8455-ba44-e15e-89c75ded526e.

For information my data source is files on a Sharepoint folder, and I already tried to change the level of confidentiality but nothing changed...

Thanks in advance for your help !

Hi @DCabaud, 

Please go to Dataflow Settings-> Data Source Credentials, specify the valid credential for the SharePoint data source. Then refresh the dataflow again to see if the issue still occurs.

Hi @v-qiuyu-msft I already tried that but I have the same issue, I tried to change the confidentiality level but nothing changed... Do you have another idea ?
