Subscribable | Lightweight JavaScript library for adding pub sub | Runtime Evironment library

I have an application which reads the data from JMS message queue and after reading the message message passed to diff async channel ( executor channels). When I stop the application it stops processing the message currently in flight and throw the error

During a planned downtime for our Kafka cluster, we basically encountered the following issue How to specify timeout for sending message to RabbitMQ using Spring Cloud Stream? (with Kafka rather than RabbitMQ, obviously).

The answer from @GaryRussell:

The channel sendTimeout only applies if the channel itself can block, e.g. a QueueChannel with a bounded queue that is currently full; the caller will block until either space becomes available in the queue, or the timeout occurs.

In this case, the block is downstream of the channel so the sendTimeout is irrelevant (in any case, it's a DirectChannel which can't block anyway, the subscribed handler is called directly on the calling thread).

The actual blocking you are seeing is most likely in the socket.write() in the rabbitmq client, which does not have a timeout and is not interruptible; there is nothing that can be done by the calling thread to "time out" the write.

The only possible solution I am aware of is to force close the rabbit connection by calling resetConnection() on the connection factory.

explains quite well why the method in question (org.springframework.integration.channel.AbstractSubscribableChannel#doSend) does not take the timeout into account. However, this still seems a bit odd to me.

In spring-integration-kafka-3.2.1.RELEASE-sources.jar!/org/springframework/integration/kafka/outbound/KafkaProducerMessageHandler.java:566, we can see that, if sync behaviour is desired:

When I try to implement this, object is created in Firebase perfectly but, .html file is not showing the output and showing error at line(below). I have also added error message below. Please help me, I am stuck at this since 2 days.

I have crafted code based on the Java DSL documentation for Spring Integration. When I run the code, I keep on getting the following warning, even though the logs also suggest that the message has been passed successfully to both subscribers.

i am using currentUserNav$ observable in an html form after i apply ! before the observable in html as below.

*ngIf="! currentUserNav$ | async"

this is the error i recieve : Overload 1 of 3, '(obj: Subscribable | Promise): unknown', gave the following error. Argument of type 'boolean' is not assignable to parameter of type 'Subscribable | Promise'. Overload 2 of 3, '(obj: null): null', gave the following error. Argument of type 'boolean' is not assignable to parameter of type 'null'. Overload 3 of 3, '(obj: Subscribable | Promise): unknown', gave the following error. Argument of type 'boolean' is not assignable to parameter of type 'Subscribable | Promise'.

the code i use in nav.component.ts :

I am trying to read .xlsx worksheets using tkinter. But code is posting error of "TypeError: 'NoneType' object is not subscribable". I have made enough trial on it but not able to understand the issue with the code.

My goal is to secure a WebSocket endpoint e.g ws://localhost:8080/chat.

What I did:

1. I tried to create WebSocket connection with STOMP

I am getting the below warning message in my boot application; what could be the issue ?

The provided errorChannel 'x.y.errors' is an instance of DirectChannel, so no more subscribers could be added and no error messages will be sent to global error channel. Resolution: Configure your own errorChannel as an instance of PublishSubscribeChannel

My config looks like this:

So, problem is with router. When the router try send message to channel I'l got the error: Dispatcher has no subscribers for channel 'newTypingNotificationHandler.input'. But I have integrationFlow defenition for this channel name.
