Object reference not set to an instance of an object

[Quest]

I have a report which uses an excel file in sharepoint as its source. When I refresh the report in Power BI desktop, I get the error 'Object reference not set to an instance of an object'. This report was working file till yesterday. Can someone help me with this? Has anything changed in the latest release of desktop?

I also get this error,

@Quest 

I tried the latest version to create a report and all seem to be working fine. Try to clear permissions in data source settings.

[Quest]

I have already tried that Option. This is only for one datasource which is accessing an xlsx file in sharepoint. 

[Quest]

I would add that any file that I access from sharepoint site is giving me this error:

Stack Trace:
Microsoft.Mashup.Client.UI.Shared.ExceptionResultException

The formula is 

shared #"Set%Tracker" = let
Source = Web.Contents("https://tenant.sharepoint.com/sites/library/folder/Shared%20Documents/folder/Set%20Tracker.xlsx")
in
Source;

Having problems in GCC as well with SharePoint datasources with the October 2021 update. Everything worked fine until today, SharePoint data sources now give the 'Object reference not set to an instance of an object' error. Reported the issue.

@Quest @v-chuncz-msft 

Just a quick followup, after troubleshooting it turns out only SharePoint datasources without HTTPS at the begining were displaying the error. Adding https:// to the start of my SharePoint datasources has resolved the issue. Hope this helps.

Same problem here (v. 2.99.621.0)

[AudLTxr]

I have the exact same issue. And all my Sharepoint data sources are in https. Any ideas ?
