App Service: "Application Error" - Cannot find module '../lib/utils/unsupported.js'

I've tried to follow these steps but the application is now saying "Application Error"

I looked at the logs and I see this:

I've deployed using Node LTS 10, 8 and 6.

I'm using DevOps to deploy:

Pipelines: Agent Pool Ubuntu 1604 Get Sources: Azure Repos npm i npm@latest npm i -g typescript ts-lint npm i npm run build

Package.js scripts:

  "scripts": {
    "start": "npm run serve",
    "serve": "node dist/index.js",
    "prebuild": "tslint -c tslint.json -p tsconfig.json --fix 'src/**/*'",
    "build": "tsc",
    "dev": "nodemon --exec ts-node src\\index.ts",
    "d": "nodemon -r esm src\\index.ts",
    "check-types": "tsc",
    "test": "echo \"Error: no test specified\" && exit 1"
  },

I googled the NPM Error and all the suggestions I found has to do with deleting Node but I'm assuming every time I push a build a new node_modules is installed so I'm not sure where to go from there.

EDIT:

So I just tried deploying it through the VS Code extension and it worked without problem. Which is great. However, I'd really like for this to working through Pipelines using DevOps so I can setup a CI/CD process. Any ideas why it might be failed through pipelines?

Can you switch to the 10? (the latest version should work OK with the 10 TLS release). We are using Node 10 with Azure DevOps at work for very different task and yet it never failed.
