Middleware hangs when using getGraphQLParams function

[mimo84]

When using the getGraphQLParams function inside a middleware function, the response hangs.
I've created a simple repo with the minimum required to replicate the issue here: https://github.com/mimo84/getGraphQLParamsBug

The code:

const express = require('express');
const graphql = require('express-graphql');
const {
  GraphQLObjectType,
  GraphQLSchema,
  GraphQLString,
} = require('graphql');

const app = express();

const schema = new GraphQLSchema({
  query: new GraphQLObjectType({
    name: 'RootQueryType',
    fields: {
      oneField: {
        type: GraphQLString,
        resolve(parent, args) {
          return 'oneField value';
        },
      },
    },
  })
});


app.use(async (req, res, next) => {
  // just comment out this line to see the request being successful
  const params = await graphql.getGraphQLParams(req);
  console.log(params);
  next();
});

app.use(
  '/graphql',
  graphql.graphqlHTTP({
    schema,
    graphiql: true,
  })
);


app.listen(1234, () => {
  console.log(`http://localhost:1234/graphql`);
});

Do you have time to open a pull request to addres this?

[mimo84]

I tried an attempt to fix it and I've created a branch with the test, however it seems that I cannot reproduce the bug in the test. Do you think I am missing something?

Is there a solution to this issue? I'm facing the same problem in a similar situation using middleware @mimo84

I'm also having the same problem. Curious if anyone has found a good workaround for parsing graphql params?

This library has been deprecated and this repo will be archived soon. It has been superseded by graphql-http.

Furthermore, if you seek a fully-featured, well-maintained and performant server - I heavily recommend GraphQL Yoga!
