How to solve this problem?

Answer 1

As you are using CI/CD to deploy your application, In the deploy task remove the slot name and replace the package with application file. Below are the samples:

From:

- name: 'Deploy to Azure Web App'
      uses: azure/webapps-deploy@v2
      with:
        app-name: 'hello-world-app-to-delete'
        slot-name: 'production'
        publish-profile: $
        package: .

To:

- name: 'Deploy to Azure Web App'
      uses: azure/webapps-deploy@v2
      with:
        app-name: 'hello-world-app-to-delete'
        publish-profile: $
        package: ./dist/hello-world-app

And to figure out what is the problem you can enable diagnostics logs in apps for azure app service. Also we can monitor our apps with Azure Application Insights.
