Cannot read property 'take' of null on KStream.stream$
I am trying to close the Stream on the given object by calling close function on the instance of class KStream
but receiving this error:
Cannot read property 'take' of null on KStream.stream$
I've also debugged that KStream.stream$
contains null
value.

import { KafkaStreams as Factory, KafkaStreamsConfig, KStream } from "kafka-streams";
interface ZStream extends KStream {
started: boolean;
}
let client = new Factory(Config as KafkaStreamsConfig);
let stream = client.getKStream("test");
async function Tester() {
const started = await stream.start();
console.log((stream as ZStream).started); // output: true
const closed = await stream.close()
console.log((stream as ZStream).started); // output: true which should be false
const startagain = await stream.start();
console.log(startagain); // output: Promise.reject => KStream is already started
const closeagain = await stream.close(); //this part sometimes create problem
}
Tester();
Hi @zeeshanalisyed thanks for the report. Are you able to provide me with a code sample of what you have so we can replicate it?

I have added the code above first of all this is produced by using client and stream as a part of the class, stream is not closed at all. but when I use class instance as a wrapper of the stream then that error is produced this is the transformed code from the real code
