We're sorry, but something went wrong.If you are the application owner check the logs for more information : When I go to update the page "localhost: 3000" at the end of the lesson happens what you see in the picture that I have attached. While if I unload "node.js" the "localhost: 3000" does not work anymore, ie it gives me this error "We're sorry, but something went wrong.If you are the application owner check the logs for more information." Why?
