maybe your localhost:4000 is already in use. You may want to kill that process.

Yes, the error indicates the port is already used. You can specify a different port in your server options

Thanks !

yarn start

works now on port 8000 but when i do

yarn dev

i've the same issues with port 3000.... why

clearly because you did the same commands in another shell before 🙂
