fatal not a git repository Windows Self-Hosted runner GitHub Actions [closed]

I am trying to run git commands on windows self hosted runner which is configured on Amazon EC2 instance. I have installed the git bash on the same machine where my runner is configured and set it's path in the Environment Variables.

Now when I am running this piece of code:

deploy:  needs: test # This test job is deployed on GitHub Hosted Runner  runs-on: [ self-hosted, Windows, X64 ]  defaults:    run:      shell: cmd  steps:    - name: Checkout code repository      uses: actions/checkout@v2    - name: Git Commit SHA command      shell: powershell      run: |        $output = C:\"Program Files"\Git\cmd\git rev-parse --short=4 HEAD        echo $output

I am getting this error: Run C:"Program Files"\Git\cmd\git rev-parse HEADfatal: not a git repository (or any of the parent directories): .gitError: Process completed with exit code 1.

I got the solution for this that I need to clone the repository inside the EC2 instance where the runner is configured and post that I need to run git init command to initialize it as a git repo but I have a reason not to clone it as being a client I don't want the third party will able to access my code.

Is there any alternative which helps me to get rid of this error?
