NuxtJS Deploy to IIS - vue.js

Question

I am trying to deploy my NuxtJS application on a new IIS server. I have installed latest Node and IISNode. Below are my web.config and server/index.js. Site Binding is on localhost:93 but I keep getting error - 'This page isn't working' http error 500. Appreciate your help.
web.config

You can control how Node is hosted within IIS using the following options:
* watchedFiles: semi-colon separated list of files that will be watched for changes to restart the server
* node_env: will be propagated to node as NODE_ENV environment variable
* debuggingEnabled - controls whether the built-in debugger is enabled
See https://github.com/tjanczuk/iisnode/blob/master/src/samples/configuration/web.config for a full list of options
