How to use createHandler with neo4j driver

[ElginHarten]

In migrating from express-graphql to graphql-http I am at a loss for how to communicate with my neo4j driver. Follow is the basics of the code I am using:

`import neo4j from 'neo4j-driver';
import { Neo4jGraphQL } from '@neo4j/graphql';
import { createHandler } from 'graphql-http/lib/use/express';

import typeDefs from './graphql/types';

const driver = neo4j.driver("bolt://localhost:7687",
neo4j.auth.basic("username", "password"));

const neo4jSchema = new Neo4jGraphQL({
typeDefs: typeDefs,
driver: driver // contains neo4j username/password
});

neo4jSchema
.getSchema()
.then((schema: GraphQLSchema) =>
{
app.use('/graphql', createHandler({ schema: schema }));
app.get('/playground', expressPlayground({ endpoint: '/graphql' }));
})
.catch((error: Error) =>
{
throw error.message;
});`

This code used to work with graphqlHTTP but after switching to createHandler queries return error "Cannot set properties of undefined (setting 'executionContext')". In looking at the code, I picked up on the idea of providing a context to connect with my database. Can anyone help me to figure this one out?

For anyone interested, the solution for hooking the neo4j driver is to write createHandler statement like so:

app.use('/graphql', createHandler({ schema: schema, context: (req) => ({ req, executionContext: driver }) }));
