I'm getting error like that:

Traceback (most recent call last):  
      File "D:\home\python364x86\wfastcgi.py", line 791, in main  
        env, handler = read_wsgi_handler(response.physical_path)  
      File "D:\home\python364x86\wfastcgi.py", line 633, in read_wsgi_handler

        handler = handler()

      File ".\ptvs_virtualenv_proxy.py", line 89, in get_wsgi_handler  
        raise ValueError('"%s" could not be imported%s' % (handler_name, last_tb))

      File ".\app.py", line 11, in <module>  
        import botbuilder  
    ModuleNotFoundError: No module named 'botbuilder'  

I don't know why it happends because i have a YAML deploy file that have pip install:

name: Build and deploy Python app to Azure Web App - azurebot-test-1  
  
on:  
  push:  
    branches:  
      - master

  build-and-deploy:  
    runs-on: ubuntu-latest  
  
    steps:  
    - uses: actions/checkout@master  
  
    - name: Set up Python version  
      uses: actions/setup-python@v2  
      with:  
        python-version: '3.6'  
        addToPath: true,  
        architecture: 'x64'  
    - name: Install Python dependencies  
      run: |  
        python -m venv env  
        cd env/Scripts/  
        chmod -R 777 ./activate  
        ./activate  
        cd ../../  
        pip install --user -r requirements.txt  
    - name: Zip the application files  
      run: |  
        sudo apt-get install zip gzip tar  
        zip -r myapp.zip .  
    - name: 'Deploy to Azure Web App'  
      uses: azure/webapps-deploy@v1  
      with:  
        app-name: 'azurebot-test-1'  
        slot-name: 'production'  
  
        publish-profile: ${{ secrets.AzureAppService_PublishProfile_8630fb021e6f4db6a8107f4c9aaca965 }}  
        package: './myapp.zip'  

And my web.config is:

I had another problem like that with other package "aiohttp", that was identical, so i added an extension with azure panel a Python 3.6x86 and changed the python path in scriptProcessor. It is solved the problem after many of cmd manipulations in new python path with manual pip installs with some flags that i can't remember, but after that problem steped to the next line of imports.
I can share my app.wsgi_app(), ptvs_virtualenv_proxy.get_virtualenv_handler() functions that used in my web.config or just say what i can share with you
