MissingCredentialScopeException when writing hail matrix table to unity volumes

Hello,

I am tinkering with using Unity Catalog Volumes with hail

I tried the following

hl_1000g.write(
    str(VOLUMES_PATH / '1kg.mt'), 
    overwrite=True
)

Where 'VOLUMES_PATH' is `Path("/Volumes") / "hail" / "volumes_testing" / "1kg"`

Unfortunately this results in the following error:

FatalError: MissingCredentialScopeException: [UNITY_CREDENTIAL_SCOPE_MISSING_SCOPE] Missing Credential Scope. Current env: Driver.

My current work around is to save the matrix table to a temp path, and then copy over to unity volumes. The reverse order is then required to read the matrix table.

Does anyone know what spark configuration might be required in order for me to read / write to this volume directly from hail?

Alexis
