Github actions failing on dependencies

Question

I tried to link my github repo to my azure function app which is typically done through the UI. However, github is throwing me some errors in the dependencies section of the build.

Run pip install -r requirements.txt
  pip install -r requirements.txt
  shell: /usr/bin/bash -e {0}
  env:
    AZURE_FUNCTIONAPP_PACKAGE_PATH: .
    PYTHON_VERSION: 3.10
    pythonLocation: /opt/hostedtoolcache/Python/3.10.11/x64
ERROR: Could not open requirements file: [Errno 2] No such file or directory: 'requirements.txt'

Notice:  A new release of pip is available: 23.0.1 -> 23.1.2
Notice:  To update, run: pip install --upgrade pip
Error: Process completed with exit code 1.

I'm very new to CI/CD, especially in this format. Any help on what it needs from me would be very helpful and appreciated. I am working on Windows with Python 3.10.6

Below is my github actions workflow file.

Thank you @Azeem and @GuiFalourd for your comments. Make sure your github repo has requirements.txt and other Function files places the same way I have in my repository here:-

Make sure to have init.py and functions.json in one separate folder and rest all the files outside of it in the root of your repo as suggested by @Azeem and @GuiFalourd like below:-

My repository:-

My requirements.txt:-

azure-functions

Now, I ran the Github Actions deployment directly via Azure Deployment Center function was deployed successfully, Refer below:-

Github workflow:-

You can find my github workflow in this Link.
