Subscriptions throw an exception on the server #2

Open nareshbhatia opened 5 years ago

Book creation results in an exception on the server:

Cannot read property 'bookService' of undefined

The underlying reason is that dataSources are not passed to resolvers during pubsub.publish()

For now, I have worked around this issue by creating a global instance of dataSources instead of passing it via context.

When was the last time you checked if this was still an issue?

Don't think there is an update from Apollo on this issue. See the comments on their roadmap, e.g. https://github.com/apollographql/apollo-server/issues/2360#issuecomment-641697135
