Traccar on VS Code

When and run npm start, dev server starts. but getting this error (https://nodejs.org/api/errors.html#errors_common_system_errors)
and when I go to access from firefox

127.0.0.1:3000. error occurred while trying to proxy: 127.0.0.1:3000/api/server

traccar has to be running locally too so that the interface in question can access the api

I did start the service

Check the REACT_APP_URL_NAME variable in the .env file of the folder where you run the npm start command if it is pointing to the traccar you want to connect

to start traccar service on vscode. I did service traccar start. is this correct

I changed the traccar port to 3000. I can see traccar blue line flashing going through on webpage, but not coming to login screen.

this website codeartisan.cloud assisted me with the full install of the dev server, modifications to the web UI. good read.
