It's possible that the authentication credentials you're using to connect to Databricks are not properly set up in your Azure DevOps environment. Here are a few things to check:

1. Make sure that you have created a Databricks access token with the appropriate permissions to perform the import operation in your Azure DevOps release pipeline.
2. Check that you're passing the access token to Databricks correctly in your import command. You can use the --token flag followed by the token value, or set the DATABRICKS_TOKEN environment variable to the token value.
3. Verify that the Databricks workspace URL you're using in your import command matches the URL you're using locally. If you're using different Databricks environments, they may have different URLs.
4. Check that your network settings allow traffic from Azure DevOps to the Databricks workspace. Depending on your network setup, there may be firewall rules that are blocking traffic from your Azure DevOps environment.
5. If none of these steps resolve the issue, try enabling debug logging in your import command to see if it provides more information about the error. You can do this by adding the --debug flag to your command.

Hopefully, one of these steps will help you resolve the authentication issue and successfully import your notebooks in your Azure DevOps release pipeline.
