'JetStream: How to make Push Subscription with Durable consumer? (i get "No interest")

I try to make Durable and Delivery consumer, but i get "No Interest" as result.

  1. It is "Active" When i create PushSubscribeOptions like this:

    PushSubscribeOptions pso = PushSubscribeOptions.Builder()

             .WithDurable(options?.DurableName)
          .WithStream(options?.StreamName)
         .Build();
     IJetStreamPushAsyncSubscription sub =
         _js.PushSubscribeAsync(options?.Subject, someHandler, true, pso);

  2. It is "No interest" when i use this code:

    PushSubscribeOptions pso = PushSubscribeOptions.Builder()

             .WithDurable(options?.DurableName)
         .WithStream(options?.StreamName)
         .WithDeliverGroup(options?.DeliveryGroup)
         .Build();

     IJetStreamPushAsyncSubscription sub =
         _js.PushSubscribeAsync(options?.Subject, someHandler, true, pso);

So , i am confuse.

Start the subscriber before you create the push consumer. At least in go, the no-interest is only an optimization (why transmit on a topic no one is subscribing on), and there it will start to push as soon as the is a subscriber ON THE PUSH TOPIC
