Error While Loading sflow_tap.lua

[yeongwei]

Hello There,

1. Below is my system details

   • Wireshark Version 1.10.14
   • CentOS Linux release 7.5.1804 (Core)

2. I am placing the sflow_tap.lua into /usr/lib64/wireshark/plugins/1.10.14

3. Upon launching Wireshark I got the following error,

Lua: Error during loading:
 [string "/usr/lib64/wireshark/plugins/1.10.14/sflow_tap.lua"]:179: bad argument #1 to 'new' (Field_new: a field with this name must exist)

4. Can anyone help?

Thank you very much!

Rgds,
YeongWei
