GitHub actions not copying Autosummary folder generated by Sphinx to new branch

Question

I have been trying to create a .yml file to automatically generate python docs with Sphinx and the Autosummary extension. This is supposed to perform just at the make html command on localhost but copy the generated HTML to a gh-pages branch to be seen on my git hub pages web page. source code

in my github/workflows/build.yml file I have

name: gh-pages auto builder
on: [push]
jobs:
  build:
    runs-on: ubuntu-latest
    steps:
    - uses: actions/checkout@master
    - uses: actions/setup-python@v2
    - name: Install dependencies
      run: |
        python -m pip install --upgrade pip
        pip install sphinx_rtd_theme
    - uses: actions/checkout@master
      with:
        requirements: src/requirements.txt
        fetch-depth: 0 # otherwise, you will failed to push refs to dest repo
    - name: add .nojekyll
      run: |
        touch .nojekyll
    - uses: actions/checkout@master
    - name: Build and Commit
      uses: sphinx-notes/pages@v2
    - name: Push changes
      uses: ad-m/github-push-action@master
      with:
        github_token: ${{ secrets.GITHUB_TOKEN }}
        branch: gh-pages

when pushing the script runs as expected and the resulting gh-pages can be viewed here

the problem is with the subpages as it is generated by the Sphinx Autosummary module and doesn't get copied to the new branch.

the output can be viewed below where Autosummary does generate the required HTML

  Running Sphinx v4.5.0
  [autosummary] generating autosummary for: _autosummary/ml_pipeline.mymodule1.myClass1.rst, _autosummary/ml_pipeline.mymodule1.myError.rst, _autosummary/ml_pipeline.mymodule1.myGlobalFunction.rst, _autosummary/ml_pipeline.mymodule1.myTypeVar.rst, _autosummary/ml_pipeline.mymodule1.rst, _autosummary/ml_pipeline.mymodule2.myClass2.rst, _autosummary/ml_pipeline.mymodule2.rst, _autosummary/ml_pipeline.mysubpackage.mymodule3.myClass3.rst, _autosummary/ml_pipeline.mysubpackage.mymodule3.rst, _autosummary/ml_pipeline.mysubpackage.mysubsubpackage.mymodule4.myClass4.rst, _autosummary/ml_pipeline.mysubpackage.mysubsubpackage.mymodule4.rst, _autosummary/ml_pipeline.mysubpackage.mysubsubpackage.rst, _autosummary/ml_pipeline.mysubpackage.rst, _autosummary/ml_pipeline.rst, api.rst, index.rst

but when it comes to copying the files over I get the output:
