I'm having issues with checking out Git repo in Workflows. 

Databricks can access files from commit `a` but fails to checkout the branch when attempting to access commit `b`. The error occurs specifically when trying to checkout commit `b`, and Databricks seems unable to access the files from this commit.

Here’s a brief overview of the problem:

• Commit `a` works fine, and Databricks can access the files.
• Commit `b` fails with an error: "Failed to checkout Git repository."
• The repository is properly linked to the Workflow Task run details.
• I’ve verified that commit `b` exists in the branch history and is accessible locally.

Could anyone offer a solution?
