cppkafka::produce not flushing

https://stackoverflow.com/questions/77996984/cppkafka-bufferedproducerproduce-not-flushing-the-queue
if someone can please tell me what is going on that will be really helpful. Or should i use Producer class instead of BufferedProducer ?? because i dont need to create our own flush mechanism where its more error prone, because lets say if there are no events and then checking based on buffer size full or not to flush will results in no flush at all.
