We are also trying to follow the instructions given here, creating a .databrickscfg file with 

[AZURE_MI_WORKSPACE]
host                        = https://XXX.azuredatabricks.net/
azure_workspace_resource_id = YYY
azure_client_id             = ZZZ
azure_use_msi               = true

And removing the token from the function call. This - again - also works locally, while we get the error "Tried all the ports [8020, 8021, 8022, 8023, 8024] for oauth redirect, but can't find free port" when running on an Azure function.
