Error: Cannot find module '/app/apps/landing/server.js'
Goal: Being able to start an app via a global docker-compose
Problem: the build works correctly, it is the start part of the app next via
node ./apps/landing/server.js
which cannot find the server.js file
node: internal/modules/cjs/loader: 1137
throw err;

Testing
When I manually force the import of the server.js file that I would have generated locally from Docker Desktop, it works.

const path = require('path')
const dir = path.join(__dirname)
process.env.NODE_ENV = 'production'
process.chdir(__dirname)
// Make sure commands gracefully respect termination signals (e.g. from Docker)
// Allow the graceful termination to be manually configurable
if (!process.env.NEXT_MANUAL_SIG_HANDLE) {
process.on('SIGTERM', () => process.exit(0))
process.on('SIGINT', () => process.exit(0))
}
const currentPort = parseInt(process.env.PORT, 10) || 3000

As specified there is no server.js since this will be built on the image.

I have omitted the installer stage since I'm not 100% sure that it's necessary.
