Hello,
due a recent fix in git : fatal: unsafe repository ('F:/GitHub/my-project' is owned by someone else) · Issue #1735 · progit/progit2 · GitHub
It’s impossible to check out code with CircleCI if the docker target folder belongs to a different user.
This means that when you specify working_directory: in any step, and it doesn’t belong to the user that’s used for checking out the code, the entire step fails.
