When performing the steps in the Assign the application to a role, make sure that your user account has the Storage Blob Data Contributor role assigned to it.

Repro: I have provided owner permission to the service principal and tried to run the “dbutils.fs.ls("mnt/azure/")”, returned same error message as above.

Solution: Now assigned the Storage Blob Data Contributor role to the service principal.

Finally, able to get the output without any error message after assigning the Storage Blob Data Contributor role to the service principal.
