Your yml looks right. I guess there might be something wrong with the task itself.

As a workaround we can use the AzureFileCopy@3, in this version we don't need to do any extra job in Azure Web Portal.

And in preview AzureFileCopy@4, there's some difference. We need to make sure the Service Principal we use in this task have access to the Storage Account. For me, I need to navigate to Access control page and Add a role assignment(Storage Blob Data Contributor/owner role) to my Service Principal/Managed Identity:

So that the AzureFileCopy version4 could also work on my side.
