• I have searched the existing issues

Current behavior

When accessing the this on the resolve method helper within @Subscription in graphql it does not access the DI services being injected into the constructor of that resolver

Minimum reproduction code

#354

Steps to reproduce

1. Create a resolver
2. Inject some services within the constructor of that resolver
3. Add a @Subscription decorator in any method of your created resolver.
4. Add the resolve method in the @Subscription decorator and in the first argument put the this with type instance of your resolver class.
5. Try to use any method of your services being injected.
6. You can't use any because none of your services got injected into the this instance reference.

Expected behavior

You should be able to use the methods of your injected services in the this reference in the resolve method in @Subscription
