GraphiQL for Apollo Fine on Desktop, 404 on Laptop? - meteor

Question

I've got GraphIQL running fine on my desktop Mac at http://localhost:8080/graphql.
And on my laptop Mac, using the exact same code synced via Github, I show this in the console:
GraphQL Server is now running on http://localhost:8080/graphql
...which appears to indicate that graphql is connected. But accessing
http://localhost:8080/graphql brings up a 404 error:
Not Found
The requested URL /graphql was not found on this server
I even deleted my node_modules folder and reinstalled from scratch via meteor npm install.
Does this make sense to anybody?
Here's the code that sets up Apollo and graphiql:
//apollo
import express from 'express';
import { apolloServer } from 'apollo-server';
import Schema from '/imports/api/schema';
import Mocks from '/imports/api/mocks';
import Resolvers from '/imports/api/resolvers';
import Connectors from '/imports/api/db-connectors';
const GRAPHQL_PORT = 8080;
const graphQLServer = express();
graphQLServer.use('/graphql', apolloServer({
graphiql: true,
schema: Schema,
resolvers: Resolvers,
connectors: Connectors,
mocks: Mocks,
}));
graphQLServer.listen(GRAPHQL_PORT, () => console.log(
`GraphQL Server is now running on http://localhost:${GRAPHQL_PORT}/graphql`
));

Answer 1

So, this could be because you have something else running on 8080 on your laptop. Maybe try logging uncaught express errors to the console?
Another possibility is that you're not trying exactly the same URL on your desktop. Version 0.2 of apolloServer currently allows only POST requests. When you navigate to the address in your browser, it will try to send a GET request, which will result in a 404. Try spinning up graphiql on a separate route and see if you can access that.
PS: If you get a chance, you should make a PR to the repo where you copy-pasted the code snippet from, so other people won't run into the same issue ;-)

Answer 2

I used npm remove apollo-server and npm install apollo-server --save to update the apollo-server npm module, and did the same for apollo-client. I then updated to the apollo server 0.2.x code found at http://docs.apollostack.com/apollo-server/migration.html. I also updated to Meteor 1.4.x. Now the 404 error is gone.
