The stream has no active subscriptions when using camel-quarkus-smallrye-reactive-messaging

See original GitHub issue

When using camel-quarkus-smallrye-reactive-messaging to simply receive messages when new files show up in a folder I get

I tried Quarkus 1.7 and 1.8 with camel-quarkus-smallrye-reactive-messaging 1.1.0

The code is really simple as it consists of following class

package org.acme;

import java.io.File;
import java.util.concurrent.CompletionStage;

import org.apache.camel.component.file.GenericFile;
import org.eclipse.microprofile.reactive.messaging.Message;

@javax.enterprise.context.ApplicationScoped()
public class FilesMessageConsumer_1 {

    @org.eclipse.microprofile.reactive.messaging.Incoming("files")
    public CompletionStage<Void> consume(Message<GenericFile<File>> msg) {

        try {
            System.out.println(msg.getPayload());
            return msg.ack();
        } catch (Exception e) {

            return msg.nack(e);
        }
    }
}

and then application.properties have following

mp.messaging.incoming.files.connector=smallrye-camel
mp.messaging.incoming.files.endpoint-uri=file:/tmp/orders/?delete=true&charset=utf-8

as soon as file exists in that folder (/tmp/orders) it constantly throws above exception.

Any ideas what do I miss to make this work properly?

do you know if it will make it before 1.2.0?

The good news is that 2.4.0 is planned to be released tomorrow, so it should make Quarkus 1.9.0 & Camel Quarkus 1.2.0.

I encountered the same issue with pulsar component, it is a simple project…with inbound config like the following Inbound configuration in the application.yaml

mp.messaging.incoming.pulasr-test.connector=smallrye-camel mp.messaging.incoming.pulasr-test.endpoint-uri: pulsar:persistent://default/poc-topic?subscriptionType=SHARED&subscriptionName=reactive

Quarkus has the following warning 2021-02-17 22:42:53,976 INFO [org.apa.cam.imp.eng.InternalRouteStartupManager] (Quarkus Main Thread) Route: route7 started and consuming from: reactive-streams://0C994938016BAD2-0000000000000002 2021-02-17 22:42:53,982 WARN [io.sma.rea.mes.provider] (Quarkus Main Thread) SRMSG00207: Some components are not connected to either downstream consumers or upstream producers: - IncomingConnector{channel:‘pulasr-test’, attribute:‘mp.messaging.incoming.pulasr-test’} has no downstream - SubscriberMethod{method:‘com.gm.devit.drp.pulsar.inbound.IncomingConsumer#consume’, incoming:‘pulsar-test’} has no upstream

Quarkus is the latest 1.11.3.Final

================================= when I put an message to pulsar queue… It throws a similar error reported
