Error when using with Wireshark 2 on Windows 7

[thewilli]

When using your extension with Wireshark 2.0.4 on Windows 7 x64 I get the following error during startup:

Lua: Error during loading: C:\Path\To\socketio_proto.lua:4 bad argument #1 to 'new' (Field_new: a field with this name must exist).

So there seems to be a problem with the following line

websocket_payload = Field.new("websocket.payload.text")

Do I maybe have to install a Websocket extension first?

Wireshark comes with a Websocket packet dissector.

That field was removed in https://github.com/wireshark/wireshark/commit/d555aa759b9fb3199eb5822c20c86ed80c4608d3

The current Wireshark doesn't decode Websocket traffic correctly for me, so I cannot fix this issue right now. I've pushed to a new branch newer_wireshark that should work if it gets the correct data.

Can you use an old version of Wireshark? 1.99.2 predates that commit

What version of wireshark do you recommend it might work with?

Wireshark version 1.99.2 worked for me.
