@Chris Platts​ :

The error message you are seeing suggests that there is an issue with the authorization header when trying to clone the repository to the workspace storage account. This may be due to an issue with the GitCredential you added for Azure DevOps Repos access. Here are a few troubleshooting steps you can try:

1. Check that the GitCredential you added is correct and has the necessary permissions to access the repository. You can verify this by running the
2. git clone
3. command locally using the same GitCredential and checking if it works.
4. Check that the Databricks instance has been granted permission to access the Azure DevOps Repos. You can do this by checking the access policies on the repository in Azure DevOps.
5. Check that the storage account associated with the workspace is correctly configured and accessible by the Databricks instance. You can do this by trying to write a file to the storage account from the Databricks instance using the Azure Storage SDK.

Hope this helps!
