I’m trying to deploy a service using Node v18

Indeed, in settings < Configurations I have set it to node v18

The command

az webapp config show --resource-group <RG-name> --name <ServiceName> --query linuxFxVersion

confirms the version to be v18: "NODE|18.20.1"

Even the actual docker container being used seems to correspond to v18:

                                V

And yet(!), the version being used to deploy the app is v16 which of course causes the deployment to fail.

What am I missing?

Thank you!
