Subscription returns null to subscribed client #190

Hi,

Im currently stuck for several days trying to return my payload to my subscribed clients from apollo-server. Somehow the subscribed client did receive the push from server but all values are null. I have verified via 'resolve' on Subscription resolver that my payload is published correctly. But it always reaches my clients with null. I have even resorted to hardcoding my payload and pushing it manually. I have also double checked that my key in payload is 'addedPlace'. Im pretty sure somewhere between subscription resolve function & my client is where the problem is. Hope to hear from anyone who has a clue

@jomaint what was your resolution for this problem? I’m trying to figure out the same for my app.

Ran into the same symptom. Looks like you should be returning payload.addedPlace instead of payload, see https://github.com/apollographql/graphql-subscriptions/issues/113
