Cannot make docker-compose work with api and ui .env files settings

[maiieul]

I tried to launch the grand-stack-starter project with Docker by following the instructions in the README file but that didn't work.

To make it work, I had to change :
"GRAPHQL_URI=http://api:4000" in api/.env file to "GRAPHQL_URI=http://api:4000"
"REACT_APP_GRAPHQL_URI=http://localhost:4000" in ui/.env file to "REACT_APP_GRAPHQL_URI=http://localhost:4000/graphql"

I think it was because the UI could not send GET or POST requests to the server.
I might have added CORS with Express to make it work. But maybe it works without it too.
