[Bug] Function App will not work when deployed using Github Actions.

[Tylersuard]

Expected Behavior

I have been trying for days to get this to work.
I can deploy my function app from the VS Code extension and it works fine.
I am deploying using Github Actions, the exact script that is generated for me by Azure.
All my tests are passing in my Github Actions pipeline.
There are no errors in the pipeline.
It says deployment was successful. After deployment my function cannot be found.

It is SO frustrating to me that I can easily deploy using a click from VS Code, but the EXACT SAME CODE, pushed in the exact way that Azure recommends, does not work.

Hi @Tylersuard, thanks for reporting.

Are you following the Continuous delivery for Azure Function Apps using GitHub Actions tutorial?

Please note that, when deploying through the VS Code extension, remote build is used. For GitHub actions, depending on the plan, either one deploy or zip deploy is used.

The main difference in these technologies is that in your GitHub pipeline, you'll need to directly install the dependencies into the .python_packages folder like so: pip install -r requirements.txt --target=".python_packages/lib/site-packages"

An example step for installing the dependencies looks like this:

- name: 'Resolve Project Dependencies Using Pip'
      shell: bash
      run: |
        pushd './${{ env.AZURE_FUNCTIONAPP_PACKAGE_PATH }}'
        python -m pip install --upgrade pip
        pip install -r requirements.txt --target=".python_packages/lib/site-packages"
        popd

The full template can be found here: Python GitHub Actions Deployment Sample

Could you provide the full pipeline script and documentation you're using?

@hallvictoria Thank you for your help. When I was trying to set up my function app, I could not find those links that you posted. They would have been helpful.

Here is my question: when I connect my function app to my Github account in the deployment center, Azure creates a deployment workflow yaml. That yaml does not look anything like the example you showed me. Is the yaml that Azure generates during that step wrong? If so, why would Azure go to all the trouble of connecting Github and Function Apps, and then not bother to generate a correct, working yaml file?

It would be REALLY nice if I could just connect the github repo and the function app during setup and never have to touch the YAML again.
