The HTTP header ACCEPT is missing or its value is invalid - SharePoint List

Hi Lydia,

I am also experiencing a similar error. I am trying toconnect to a SharePoint List via teh SharePoint Online List in Power BI. THe list opens okay in the Query Editor, howevever, when I close the Query Editor window and apply the changes, I get the aforementioned error message in mwand's original post.

I am connecting to the SharePoint List using Windows authentication (AD) user credentials I believe. The columns contain mostly text and some numbers, but the datatype is general (any).

Any way to fix or otherwise resolve this issue?

Thanks
