onConversation Create and onConversation update Events trigger issue

Hi Team,

We have created a custom app, in which app perform certain action based “on conversation create” event in the freshdesk.

But the event did not get triggered for few replies to a conversation by the agent.

To confirm this issue, we checked by replying to the conversation of a ticket and we have seen that, for few agent replies only "onConversation update " event getting triggered and for some replies both “onconversation create” and “onconversation update” events getting triggered at same time. And for some replies only “onConversation Create” event got triggered.

Please find the screenshot of the App’s log for reference.

Thanks,
Suman C.
