Okay, so our datahub is running v0.10.4. My Datahub CLI version is 0.10.4 and Python is 3.11.4. Running an ingest of my yaml file (which has worked fine in other version setups gives me: Command failed: Failed to find a registered source for type powerbi: mutable default <class 'datahub.metadata.schema_classes.NullTypeClass'> for field datahubDataType is not allowed: use default_factory Downgraded python to 3.10 and it now runs, so looks like 3.11 is not working.
