So I did U2M authentication for account-level operations -

databricks auth login --host <account-login-url> --account-id <account-id>

then I tried to run code-

workspaces = account_client.workspaces.list()
workspace_obj=account_client.get_workspace_client(workspaces[0])

I got error saying -

ValueError: databricks-cli auth: cannot configure default credentials, please check https://docs.databricks.com/en/dev-tools/auth.html#databricks-client-unified-authentication to configure credentials for your preferred authentication method.

I am not sure what's going wrong here

Hi @vaishalisai,

Could you please run below validations?

Run this command to validate: databricks auth describe

Check the Databricks Configuration File: Ensure that your .databrickscfg file is correctly configured. This file should be located in your home directory and should contain the necessary credentials. The file should look something like this: [DEFAULT] host = https://<your-databricks-instance> token = <your-personal-access-token>

Verify Environment Variables: Make sure that the environment variables DATABRICKS_HOST and DATABRICKS_TOKEN are set correctly. These variables should point to your Databricks instance and contain your access token, respectively.

Unified Authentication: According to the documentation, you should ensure that you have configured the unified authentication method correctly. You can refer to the detailed steps in the Databricks documentation here: Databricks Client Unified Authentication.

OAuth for Users (U2M): Since you mentioned using U2M (User-to-Machine) authentication, ensure that you have followed the steps to generate an OAuth code verifier and challenge pair if required. This is necessary for the OAuth authentication process.
