SharePoint Integration Error

Hello! I'm getting this error while setting up my integration. I have a couple of integrations in my application that allows users to archive and download documents from a SharePoint and they both use the same connected system that I have in this one. The one I'm showing is for my own testing purposes. I'm using this integration to see if I can retrieve any folder metadata but I keep getting this error. The connected system says it's connected and I'm using Entra ID. My question is am I doing something wrong here or does it look like I have everything set up correctly? Trying to find out if there's something missing on the Appian side of things or if there's something missing on the Azure side.
