Example :
42/,["current_event",{"current_event":"onboarding","eligible":true,"isOnBoarded":true,"event":"5f4dba217f63c00bd40bd636","contestantor":"5f4dba147f63c00bd40bd635","lastContestantor":false}]
What are these starting numbers (42/,43/ etc)? and how to write proper request body in Websocket request-response sampler?
