ms-azuretools-vscode ZipDeploy of production distribution causes Oryx errors

Question

I am trying to deploy a frontend app to azure app service. When I try to push a zip deploy output of a dist build(using rpm run build) from vscode to nodes runtime azure app service, I get an error below and the app service container stopping in the logs. What is causing this as I am not trying to ask the runtime to build the code(so kudu should just deploy it), although in vscode output it shows the app has been deployed successfully?

Error: Couldn't detect a version for the platform

'nodejs' in the repo.

The app service oryx run command is as follows:

oryx build /tmp/zipdeploy/extracted -0 /home/site/wwwroot --platform nodejs --platform-version 20 -p virtualenv_name= --log-file /tmp/build-debug.10g

-i /tmp/8ds3116e54a3b6 -p compress_node_modules-tar-gz | tee /tmp/oryx-build. 10g

Hi @Chandan Datta
Thanks for the question and using MS Q&A platform.
apologize for any inconvenience caused on this.
The error message Error: Couldn't detect a version for the platform typically indicates that the Oryx build process is unable to identify the Node.js version specified for your application. This can happen if the package.json file is missing or if it does not specify a valid Node.js version.

To resolve this issue, ensure that your package.json file is correctly configured and includes a valid engines field that specifies the Node.js version.
1.Set Node.js Version:

Set the WEBSITE_NODE_DEFAULT_VERSION app setting to a stable version (like 16.x) using the Azure CLI:

az webapp config appsettings set --name <app-name> --resource-group <resource-group-name> --settings WEBSITE_NODE_DEFAULT_VERSION="16"

2.Ensure All Dependencies Are Included:

If using TypeScript or other build tools, ensure that all necessary compiled files are included in your deployment package.
