I’m getting an error when deploying EchoBot to the Azure App Service via VS Code. Module not found.

I am trying to deploy a Python code based on Echo Bot from Bot Framework on Azure App Service.

It looks like it isn't installing the dependency 'aiohttp' I put on requirements.txt. I already added SCM_DO_BUILD_DURING_DEPLOYMENT=true to App Settings. I believe that I need to create some deployment script, but I don't know how to do it.

I pasted below the startup log with some errors that may help to diagnose my problem:

    Hello Leo Pabon,

    Welcome to the Microsoft Q&A and thank you for posting your questions here.

    Problem

    I understand that you are having an error when deploying EchoBot to the Azure App Service via VS Code "Module not found".

    Solution

    Based on the information you provided, it signifies that error you're experiencing suggests that the aiohttp module is not being installed during your deployment to Azure App Service. To simplify the process to ensure that your dependencies, including aiohttp, are installed during deployment to Azure App Service, you can use the built-in functionality of Azure to handle your application's dependencies without the need for a custom script.

    I put together the few steps to accomplish this in the followings:

    1. Make sure your requirements.txt file lists all the necessary dependencies in plain text: aiohttp==3.8.1 gunicorn==20.1.0
    2. Azure App Service can automatically install the dependencies listed in your requirements.txt file if you ensure the setup is correct. This often involves making sure Azure's deployment process is correctly configured to find and use your requirements.txt. So, place your requirements.txt in the root directory of your project. Azure App Service looks for this file to install dependencies.
    3. Go to your App Service in the Azure portal, navigate to "Configuration" > "Application settings", and ensure the following settings are present:
      • SCM_DO_BUILD_DURING_DEPLOYMENT=true
      • WEBSITE_RUN_FROM_PACKAGE=1 (optional but can help streamline deployments)
      After the above, make sure the startup command in your App Service configuration points to your application’s entry point. For example: gunicorn --bind 0.0.0.0 --worker-class aiohttp.worker.GunicornWebWorker --timeout 600 app:APP
    4. Use the Azure App Service updated extension in Visual Studio Code to deploy your application. Ensure you login into your Azure account in VS Code as you have done before.
    5. After deployment, monitor the logs in the Azure portal to ensure your app is starting correctly and that all dependencies are installed. You can view the logs by navigating to your App Service and selecting "Log Stream".

    Hello Leo Pabon

    Thanks for reaching out to us, could you please share the code sample you are working on so that we can reproduce your issue?

    I have seen the same issue when the package has been added successfully or not added in the right environment. Could you please try this as well?

    pip3 install aiohttp
    

    Regards,

    Yutong
