I already observed that when the second response arrived the `isActive` predicate returns `false` but I don't know how to prevent it

your channel has been closed too early. you should suspend inside `produce` block. for example with internal channel reader like this:
```
val channel = Channel&lt;List&lt;T&gt;&gt;(Channel.UNLIMITED)
 for (any in channel) {
            offer(any)  // here you cast data outside
        }
```

and inside your callbacks should use this internal channel:
```
channel.offer(blabla)
```

or maybe just add `delay(Long.MAX)` to the end of `produce` block. not really sure if it will work
