Good Day,
Anyone seen an error like this? Started happening this morning, I think it might be permissions related? If anyone could confirm I'd most grateful.
DataSource.Error: Web.Contents failed to get contents from 'https://linccymruadmin.sharepoint.com/team-sites/ICT-team/_api/web/lists/getbyid('6f350673-e2e1-4368...' (500): Internal Server Error
Details:
DataSourceKind=SharePoint
DataSourcePath=https://linccymruadmin.sharepoint.com/team-sites/ICT-team
Url=https://linccymruadmin.sharepoint.com/team-sites/ICT-team/_api/web/lists/getbyid('6f350673-e2e1-...
Solved! Go to Solution.
Hi @Darren_Linc,
Can you connect to a SharePoint list with the same URL successfully? Does it work?
Based on my research, this error is most likely related to SharePoint side. Please use Fiddler to capture a network trace of the request that's being sent to the SharePoint server. In order to get the Fiddler trace, you need to start Fiddler, enable the Tools > Fiddler Options > HTTPS > Decrypt HTTPS traffic option, start the capture, reproduce your issue, then stop and save the capture.
If possible, you can also update Power BI desktop to latest version for a test.
Regards,
Yuliana Gu

Thank you Yuliana, it would appear that it's an issue on the SharePoint side, as a result I've decided to remove the problem and start utilising Onedrive in the PBI shared workspace that we use. I'm thinking this will be a better long-term option too.
Hi there. I have the same error (did not experience this previously, but now I am). What I find odd is that I can connect to a subsite using the SharePoint folder connector, but not the parent. I can also connect to the parent using the web interface, but not Power BI desktop....
Is there a setting or configuration on the SharePoint side that I am missing?
I have the same error. What is strange is I can use the SharePoint folder connector to connect to a subsite, but I get the same error above when trying to connect to the parent site. Is there a setting or configuration I am missing?
