What can an error like this be related to?? It happens when I connect to a ktor server sent event and happens when I send my event exactly the 7th time.
```java.lang.ArrayIndexOutOfBoundsException: Index -1 out of bounds for length 1
	at io.ktor.util.pipeline.SuspendFunctionGun$continuation$1.getContext(SuspendFunctionGun.kt:51)
	at io.ktor.util.pipeline.SuspendFunctionGun.getCoroutineContext(SuspendFunctionGun.kt:17)

	at kotlinx.coroutines.BuildersKt__Builders_commonKt.launch(Builders.common.kt:52)

Hey! It looks like a problem in Ktor pipelines, could you tell me if you’re using client or server?

&gt; It happens when I connect to a ktor server sent event and happens when I send my event exactly the 7th time.

The piece of code that causes the error
```    call.response.cacheControl(CacheControl.NoCache(null))
    call.response.header(HttpHeaders.Connection, "Keep-Alive")
    val ipv4 = call.request.origin.remoteAddress
    println("Connected: $ipv4")
    var subscriber: Subscriber? = null
    call.respondBytesWriter(contentType = ContentType.Text.EventStream) {
        subscriber = bus.subscribe("*") {
            launch {
                writeStringUtf8("id: ${it.topic}\n")
                writeStringUtf8("event: message\n")
                writeStringUtf8("data: ${it.data}\n")
                writeStringUtf8("\n")
                flush()
            }
        }

        while (isActive) { // keep alive for future events
            delay(1000)
        }
    }
    subscriber?.unsubscribe()
    println("Disconnected: $ipv4")```

It could be an issue with an inner `launch` , <@U017TSBJ2C9> could you please check?
