React Native Debug in Expo - Failed to connect to /


I created my app in Visual Studio code using npx create-expo-app AwesomeProject.
When I start the application using npx expo start and go to Expo Go, I can see my application and use it.

I tried to configure the debugger and ended up with a launch.json file like this :

            "version": "0.2.0",
            "configurations": [
                    "name": "Attach to packager",
                    "request": "attach",
                    "type": "reactnative",
                    "cwd": "${workspaceFolder}"
                    "name": "Debug in Exponent",
                    "request": "launch",
                    "type": "reactnative",
                    "cwd": "${workspaceFolder}",
                    "platform": "exponent",
                    "expoHostType": "local"

In Visual Studio Code ‘Run and Debug’ menu, I start the debug using ‘Debug in Exponent’ and when I scan the QR Code and try to debug the app in Expo Go I have an error saying ‘Uncaught Error: Failed to connect to /’
I tried to delete the .expo folder as suggested in some other posts but it didn’t work.
