Visual Studio Data Connector Sharepoint.Contents Function Credentials

Hi,

I'm working on a data connector that uses sharepoint and one drive files to connect to data, and then runs power query functions on the files available. I can't seem to connect to the sharepoint list. The credentials prompt continues to show no matter what I select.

Ex. using the following query will prompt the credentials screen to show over and over again. This  occurs no matter what credentails I supply.

sharefolder = () as table =>
let
source = SharePoint.Contents("https://xxxxxx-my.sharepoint.com/personal/xxxxx/")
in
source;

Any help would be greatly appreciated. Thank you.
