Retrieving task details from Migration Manager (Fileshare Migration) no longer work via Powershell

Question

https://learn.microsoft.com/en-us/sharepointmigration/mm-reports#download-detailed-task-level-reports-via-powershell

in the Function GetAlltasks there no longer retrieve Data from MS Graph and it gives no error Message so the Script get error, that no Tasks found

I think behind the scenes there is a problem accessing the Graph API via Powerhshell, however when I call the URI in the browser I can get the data there. I also had the new role of Migration Manager assigned to me without any effect

I need a solution. I use the script to prepare the log files for the end users
