Could not validate drive id - no other details

My task is failing with the message "Could not validate drive id" but then provides no further details:

The output of the key parts of a debug log are below

I have tried lots of different formats for the SharePoint URL e.g. trailing slashes replacing %20 with a space etc. but nothing seems to work. I think I have my client secret correct as I have tried replacing that with gobbledegook and it failed with a 401 error.

I've had a couple of private messages about this. I still have not been able to resolve this issue.

Hi, I have to find out why the logged error is empty - currently I have no idea...

Hi @halliba, Do we have to add azure ad client id, tenant id and client secret id in sharepoint online too?
