DataSource.Error: SharePoint: Request failed

 Hi,

I created a report in PowerBI desktop, which connects to a SP2010 and retrieves data from sharepoint lists.

Everything works fine, but yewsterday when I want to refresh data in one list, I got following error. I use different lists in the same directory and I got this error only one list. I tried to create new connection in a blank PBIX and the same error appears again.

Here is the error:

Hi @obesli,

I have just deleted the calculated column from my share point site library  then the problem solved.

Were there any updates on that list recently? Could there be any calculated columns added on that list? Here is a similar thread, could you go to check if it helps in your scenario?
