Had the same problem.

In subscription.js, add console.log(schema) in the beginning. It will likely be undefined.

My solution: My Imports in index.js were in the wrong order. You must first import subscriptions.js, and only then `schema.js´.

from graphql-subscriptions.

It might be a circular dependency issue.

from graphql-subscriptions.

So I adjusted the way I was loading the subscriptionServer, particularly removing the http.createServer and loading my express app as the server:

new SubscriptionServer({
	subscriptionManager
}, {
	server: app
});

Otherwise I adjusted the setupFunctions and it appears to be working now!

// subscriptions.js
import { PubSub, SubscriptionManager } from 'graphql-subscriptions';

import schema from './schema';

const pubsub = new PubSub();

const subManger = new SubscriptionManager({
	schema,
	pubsub,
	setupFunctions: {
		todoAdded: (options, args) => ({
			newTodosChannel: {
				filter: todo => todo.id
			},
		}),
	},
});

subManger.subscribe({
	query: `subscription todos($completed:Boolean) {
				todoAdded(completed:$completed){
					id
					title
					completed
				}
			}`,
	variables: {
		completed: null
	},
	callback: (err, data) => {
		if (err) {
			console.log(err)
		}
	}
});

pubsub.publish('newTodosChannel', {
	id: 123,
	title: 'testing graphql subscriptions',
	completed: false
});

export { subManger, pubsub };
