Visual Studio Code – Application Error when deploying python 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 already:

  • Put aiohttp on requirements.txt
  • Added SCM_DO_BUILD_DURING_DEPLOYMENT=true to App Settings.

I believe that I need to create a deployment script, but I don’t know how.

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

    I solved this by configuring GitHub continuous integration for my web app. The actions file had a step that installed all dependencies present on requirements.txt.

    The error report shows that aiohttp module is not found. Ensure that this module has been installed correctly.

    Please check your requirements.txt file. Make sure that aiohttp is listed in your requirements.txt file and that the file is located in the root directory of your application.
