I upgraded to Angular 17 and now ng serve does not run in dev mode, no source map is available. I tried every possible solution I found online related to proxy config, package.json, angular.json. I finally made it at least run and load icons and fonts, but no source map, the console log prints true which means still in production mode despite all the config settings (console.info(environment.production);). Below my project files (confidential info is replaced)
Angular 17.3.12 Node.js 18.20.7
I tried different options and their combinations in all those files, a couple of different node.js versions. I tried using routing function in proxy config but that did not help either. By now, I think I included all possible options that are out there.
With current config settings, at least the page is rendered correctly, all icons, fonts are loaded. PDF file (EULA) is loaded. But it all seems are fetched from the remote server, not my local/dev environment. The dev tools do not show any local source files, no source code changes are reflected on a reload, even though it recognizes that changes did happen.
I spent almost two weeks trying to make it work. Any constructive solution would be truly appreciated. Thank you in advance!!!

Reset to default 0I found some solution on Github and it worked for me as well. Not ideal, it seems working.
Replace 'browser-esbuild' with just 'browser' in angular.json:
"architect": {
"build": {
"builder": "@angular-devkit/build-angular:browser",
