LUA script for detecting self-signed certificates cannot load

Hello to everyone,

I am trying to adopt lua script for detection of self-signed certificates as mentioned in this post Finding self signed TLS certificates - Suricata and Luajit scripting, so I downloaded the lua script from this link:

placed the script file name in suricata.yaml file, restarted suricata docker container and got an error:

[1 - Suricata-Main] 2024-10-29 16:07:26 Info: output-lua: enabling script self_signed_cert.lua
[1 - Suricata-Main] 2024-10-29 16:07:26 Error: output-lua: unknown key and/or value: k=‘tls’, v=‘true’
[1 - Suricata-Main] 2024-10-29 16:07:26 Error: output-lua: couldn’t initialize script
[1 - Suricata-Main] 2024-10-29 16:07:26 Warning: runmodes: output module “lua”: setup failed

which means that TLS package cannot be found from init function that loads tls package:

function init (args)
local needs = {}
needs[“tls”] = tostring(true)
return needs
end

I was doing a little reserach and found no difference in Suricata 8 documentation so there should be no reason not to load this part of code.

Because I couldn’t find any related documentation that leads to this error I decided to ask if did you had this issue and how can I resolve it?

Below I left some info about the installation:
