    Thanks for asking question! As I can see from above there is ModuleNotFoundError: No module named 'application'

    This means that Python could not find one or more of your modules when the application started. This most often occurs if you deploy your virtual environment with your code. Virtual environments are not portable, so a virtual environment should not be deployed with your application code.

    Instead, let Oryx create a virtual environment and install your packages on the web app by creating an app setting, SCM_DO_BUILD_DURING_DEPLOYMENT, and setting it to 1. This will force Oryx to install your packages whenever you deploy to App Service.

    For more information, please see this article on virtual environment portability.

    Check this document link on more details on troubleshooting : https://learn.microsoft.com/en-us/azure/app-service/configure-language-python#troubleshooting

    Let us know if further query on this or issue remains.

    Hey,
    After the previous error, i got this error - "Create Artifact Container failed: Artifact storage quota has been hit. Unable to upload any new artifacts" - this one is i can see on my Github when the push request if failed. I understand that I need to delete artifacts but I did not understand how to do it..
