Hi

I am getting two issues while running SSE:

1. [ERROR] a.a.OneForOneStrategy - Actor io.gatling.http.action.async.sse.SseActor@50398382 doesn’t support message OnMessage
2. Even if 5 checks are done, gatling is still running , i am using this check “.check(wsAwait.within(10).until(5)”

Please let me know if any other info is required to check on it.

Thanks & Regards  
-Fahim

Can you share a reproducer?  
Don’t you have an Exception in the logs prior to the error you mention?
