Can't get messages in JS mode about natscli

[ripienaar]

Please show stream info of the stream listening on that subject?

check error on js.Subscribe()

[boskiv]

Thanks @ripienaar .
I did not eve create a stream.
Do you know what FATA[0000] nats: filtered consumer not unique on workqueue stream means ?
I tried to change a name in code, but it does not help

[ripienaar]

What language do you ise

[boskiv]

Golang.
looks like as nats-io/nats.js#461

I got this error when second consumer starting

[ripienaar]

The clients have some unintended consequences where it makes consumers for you. Probably what happens is the 2nd one tries to make a new consumer rather than attach to existing.

Maybe if you share the code @wallyqs can help

[boskiv]

func (n Nats) Init()  {
	log.Info("NATS init")
	// Connect Options.
	opts := []nats.Option{nats.Name("NATS Sample Subscriber 2")}
	opts = setupConnOptions(opts)

	// Connect to NATS
	nc, err := nats.Connect(n.Host, opts...)
	if err != nil {
		log.Fatal(err)
	}

	// Create JetStream Context
	js, _ := nc.JetStream(nats.PublishAsyncMaxPending(256))


	// Simple Async Ephemeral Consumer
	_, err = js.Subscribe("NATS.Positions", func(m *nats.Msg) {
		fmt.Printf("Received a JetStream message: %s\n", string(m.Data))
	})
	if err != nil {
		log.Fatal(err)
	}

	if err := nc.LastError(); err != nil {
		log.Fatal(err)
	}

	log.Printf("Listening on [%s]", PositionTopic)
	runtime.Goexit()
}

But I want to start a new second consumer and balance messages inside a stream between 2 and more consumers. As I expected in WorkQueue stream type

[ripienaar]

You should instead have 1 consumer and connect many clients to it.

[boskiv]

Do you have some example maybe in github ?

[ripienaar]

Closing this, perhaps ask in slack or on the client you use discussions or something, it's not really CLI related I think.
