gqlgenのissue下書き

[figboy9]

What happened?

Can't return an error that occurred in the other goroutine.
For example, redis-pubsub, gRPC client streaming, etc.

What did you expect?

I want to return an error after returning a channel.

Minimal graphql.schema and models to reproduce

type Subscription {
  messageAdded: Message!
}

type Message {
  id: ID!
  body: String!
}

func (r *subscriptionResolver) MessageAdded(ctx context.Context) (<-chan *model.Message, error) {
	ch := make(chan *model.Message)
	go func() {
		// some kind of block processing (e.g.: gRPC client streaming)
		stream, err := gRPCClientStreamRequest(ctx)
		if err != nil {
			log.Println(err) // i want to return this error
		}
		for {
			m, err := stream.Recv()
			if err != nil {
				log.Println(err) // i want to return this error
			}
			ch <- m
		}
	}()
	
	return ch, nil
}
