[Bug]: Deployment App Service (code) doesn't work as documented #3712

Description

@appscontrol

What happened?

I followed the instructions to the letter in the documentation for Deployment - App Service (code) but the App Service whilst created and configured as instructed fails to start. It appears to be an issue with it expecting SDK to be installed? Errors on startup
