I am trying to create a compute instance, but keep receiving the message

The specified Azure ML Compute Instance andrewnam1 setup failed with error "Failed to mount storage. Details - Hint:Miss required permission Storage File Data Privileged Contributor, please find your admin to assign the permission to a2cc1573-f31d-470f-8b39-73a3a7fc4bd8 ". Please delete and try to recreate. If the problem persists, please follow up with Azure Support.

    The error message you are encountering indicates that the Azure ML Compute Instance setup failed due to insufficient permissions related to storage access. Specifically, the error suggests that the user needs the "Storage File Data Privileged Contributor" role assigned to the relevant Azure Active Directory (AAD) user or service principal to successfully mount the storage.

    To resolve this issue, you should follow these steps:

    1. Contact your Azure administrator to request the necessary permissions. They can assign the "Storage File Data Privileged Contributor" role to your user account or the service principal associated with the compute instance.
    2. Delete the failed compute instance and attempt to recreate it after the permissions have been updated.
    3. If the problem persists after ensuring the permissions are correctly set, consider reaching out to Azure Support for further assistance.

    It’s also worth noting that if others in your team are experiencing similar issues, they will need to ensure they have the same permissions as well.
