GraphiQL endpoint broken after migrating to 0.2? "Apollo Server supports only POST requests"

[sebastienbarre]

Hi guys. Thanks for the great work!
My small Apollo server example was working fine at 0.1, but after following the exact migration path to 0.2 and double checking against the Apollo Server GraphiQL docs page, the server no longer seems to serve GraphiQL correctly.

The page: localhost:9090/graphql always returns Apollo Server supports only POST requests and the GraphiQL GUI never shows up.
Now it's unclear to me if both can be at the same endpoint, as stated in both examples in the doc:

graphQLServer.use('/graphql', bodyParser.json(), apolloExpress({
  schema: executableSchema,
}));
graphQLServer.use('/graphiql', graphiqlExpress({
  endpointURL: '/graphql',
}));

but changing the GraphiQL endpoint to '/graphiql' will bring the UI back, but executing any GraphQL example there will still fail.
Thanks

What error message do you get when executing a query from /graphiql? Does the network tab show that a request to /graphql is made from the GraphiQL UI?

This looks like a user error on my side, my apologies. I must have tried the /graphql endpoint first, be confused by the message, modified the code, then tried the /graphiql, which I had broken already by changing the endpointURL. Closing (feel free to nuke the issue entirely).
