Azure Functions dis-appeared from the Function App and I am not able to push functions from local folder to function app.

Question

As you can see in the image I have more functions showing in the local project folder but less in my function app. Previously I had the same count. Suddenly some functions disappeared from the app and now when I deploy the functions again it says successful deployment but can't the functions in the function app.

Python Interpreter installed on my machine: 3.8.5
Azure Function App runtime version: 4

Deployment Logs are also attached below:

Hi @Ammad Niazi

Check that your deployment artifacts are not empty. It happens that the build pipeline can generate an empty deployment artifact file. Sometimes restarting your Function App in the Azure portal can resolve issues with functions not appearing.

If it still doesn't resolve, you may check by Syncing Triggers. Send an HTTP POST request to https://{functionappname}.azurewebsites.net/admin/host/synctriggers?code=<API_KEY> using the master key to sync the triggers.
