Production deployment

We use this script to bundle the web-ui in the GNS3 server: https://github.com/GNS3/gns3-server/blob/3.0/scripts/update-bundled-web-ui.sh

However nothing can be seen when opening a browser to point to the server IP/port. I can see some .js and .css files are sent from the server but nothing is displayed. This works when bundling v2 of the web-ui, so I am definitely suspecting something is wrong with v3.

I have also tried to manually deploy and running a small http server in the web-ui repo directly:

yarn ng build --configuration production
yarn run v1.22.19
$ ng build --configuration production

This is the same result, files are served by the HTTP server but nothing is displayed in the browser. The only "error" I can see when building is this one, maybe that's the reason?

It works after adding --build-optimizer=false to the build command line.

So now need to understand what is this optimizer and if we need it?

Also, need to investigate these 2 errors/warnings:

⠋ Generating index html...1 rules skipped due to selector errors:
  legend+* -> Cannot read properties of undefined (reading 'type')

./node_modules/bootstrap/dist/css/bootstrap.min.css.webpack[javascript/auto]!=!./node_modules/@angular-devkit/build-angular/node_modules/css-loader/dist/cjs.js??ruleSet[1].rules[4].rules[0].oneOf[0].use[1]!./node_modules/postcss-loader/dist/cjs.js??ruleSet[1].rules[4].rules[0].oneOf[0].use[2]!./node_modules/bootstrap/dist/css/bootstrap.min.css - Warning: Module Warning (from ./node_modules/postcss-loader/dist/cjs.js):

The last one seems to be a consequence of deactivating --build-optimizer=false...
