Hi Sergio!

In FinCore\ClientApp folder, I run "npm start" with admin previlegies, but the following error occurred:

LOG:
[error] Error: listen EACCES: permission denied 0.0.0.0:4200
at Server.setupListenHandle [as _listen2] (net.js:1299:21)
at listenInCluster (net.js:1364:12)
at doListen (net.js:1501:7)
at processTicksAndRejections (internal/process/task_queues.js:81:21)

If I try a "npm install" again in "ClientApp" folder, then this other error occurs:

npm ERR! code EBADPLATFORM
npm ERR! notsup Unsupported platform for fsevents@2.1.3: wanted {"os":"darwin","arch":"any"} (current: {"os":"win32","arch":"x64"})
npm ERR! notsup Valid OS: darwin

I solved all my problems uncommenting all these lines in Startup.cs:

`

                spa.UseAngularCliServer(npmScript: "start");

                spa.UseProxyToSpaDevelopmentServer(Configuration["DebugClientURL"]);
                

                spa.UseProxyToSpaDevelopmentServer(Configuration["ExternalClientURL"]);`
