No, they just don't work, I get login but now return another error, Type error on a function Uma graphql where trow errors

Is the docker container up?

Yes, I do all the steps, but "make in" doesn't work, so I keep going and start next.js, the login screen appears but I can't go forward. Drupal works fine.

When you try to login the POST request is sent to what address?

Redirect to the root, on my case localhost:3000, te full error message is: I handled rejection(type error): err.graphQLErrors[0] is undefined

[marcosvlehmkuhl]

So I believe the problem is since you are running the Next.js outside the container, localhost:3000/graphql is not a valid endpoint because the graphql server is inside the container. Setting the GRAPHQL_HOST variable to http://${docker-container-ip}:3000 should work.

What is the error when you make in?

Error: docker exec requires at least 2 arguments

Setting the variable gives another error: only absolute URLs are supported

[marcosvlehmkuhl]

Sorry, my mistake, the GRAPHQL_HOST shoud not have the port so it should actually be http://${docker-container-ip}/graphql

And you also have to remove the port 3000 mapping from the app container.

About the make in error it occurs when the terminal window is too small 😛.
But you could enter the container with docker exec. All you gotta do is run docker ps and get the container id, and then docker exec -it ${container_id} /bin/bash
