Conversation API unavailable in Lua Scripts?

asked 2025-10-06 14:59:11 +0000

HI Everyone,

I'm currently working on writing a dissector for a custom protocol and I"m trying to use the Conversation API. I can see the API in the documentation and GitHub history, but I can't seem to use it in my Lua script. If I do Conversation.find_with_pinfo(pinfo,true) I get this error:

.local/lib/wireshark/plugins/wgproto.lua:21: attempt to index a nil value (global 'Conversation')] [Severity level: Error] [Group: Undecoded] Lua Traceback

I also can't access the Conversation global in the Lua console. I reinstalled WireShark yesterday from the main website, as far as I can tell the Conversation API should be in it as the API was merged in 7 months ago.

Anyone know what I can do?

Thanks Chuckc - I now see that I have version 4.4.x which does not include that commit, I will try to build a dev build
