Hi, cloned the repo and had to make a series of changes to get the front-end (client app) to compile.
Note: I can provide details if need be.

Question: what is the "debug" workflow/process you are using for the front-end app?
I'm getting the following error when I try to debug the angular app through VS code:

Error:
/usr/share/nginx/html # node --inspect-brk=0.0.0.0:9229 main.js
Debugger listening on ws://0.0.0.0:9229/c10c49bc-2c46-47ee-80cb-97c20c7a52bb
For help, see: https://nodejs.org/en/docs/inspector
Debugger attached.
Waiting for the debugger to disconnect...
/usr/share/nginx/html/main.js:1
(self["webpackChunkaccess_point_map"] = self["webpackChunkaccess_point_map"] || []).push([["main"],{
^

A few observations:

1. no webpack.config that I can see
2. had to extensively change DockerFile (see below) so that I could use 1 image that contains 'node' v14 installed so that we could remote debug once app is deployed inside container....
