databricks OAuth is not supported for this host

I'm trying to deploy using Databricks Asset Bundles via an Azure DevOps pipeline. I keep getting this error when trying to use oauth:

Error: default auth: oauth-m2m: oidc: databricks OAuth is not supported for this host. Config: host=https://<workspace>.azuredatabricks.net, client_id=***, client_secret=***. Env: DATABRICKS_HOST, DATABRICKS_CLIENT_ID, DATABRICKS_CLIENT_SECRET ##[error]Bash exited with code '1'.

The pipeline is nothing complicated:

trigger: - development pool: vmImage: ubuntu-latest variables: - group: "DevOps Service Credentials Databricks" stages: - stage: "Development_Deploy" jobs: - job: "Deploy_Bundle" steps: - script: | curl -fsSL https://raw.githubusercontent.com/databricks/setup-cli/main/install.sh | sh displayName: 'Install Databricks CLI' - script: | databricks bundle deploy displayName: 'Deploy Databricks Asset Bundle' env: DATABRICKS_HOST: https://<workspace>.azuredatabricks.net DATABRICKS_CLIENT_ID: $(databricksdevopsdeployment-clientid) DATABRICKS_CLIENT_SECRET: $(databricksdevopsdeployment-clientsecret)

Any ideas? What am I doing wrong?

I can confirm that the host/clientid/clientsecret are correct as I can use the same variables with az login and it connects to the workspace successfully; I just get a different error of "cannot create default credentials" for the a job after it successfully uploads the bundle files. Is there a setting I need to check to enable oauth for a given workspace?

Hi @bradleyjamrozik, thank you for posting your question. You will need to use ARM_ variables to make it work

Specifically

ARM_CLIENT_ID ARM_TENANT_ID ARM_CLIENT_SECRET

https://learn.microsoft.com/en-us/azure/databricks/dev-tools/auth#environment-3 for reference,

Hope that helps!

So in this case the Azure managed identities authentication needs to be used?

@saadansari-db , do we need a Azure Databricks managed service principal or Microsoft Entra ID managed service principal to run bundles deployment?
