Can't use TriggerServerEvent?

FiveM Server Development Resource Support

So I’m new to this and recently I’ve downloaded this script. First I tried creating a command which plays a sound for me, but I failed.
kép A screenshot from the directory.
This is the command in my client main.lua:

RegisterCommand("playSoundFM", function(source,args)
    print("debug1")
    TriggerServerEvent('InteractSound_SV:PlayWithinDistance', 1.0, 'seatbelt-buckle', 1.0)
end, false)

And in server main.lua file this is the event:

RegisterServerEvent('InteractSound_SV:PlayWithinDistance')
AddEventHandler('InteractSound_SV:PlayWithinDistance', function(maxDistance, soundFile, soundVolume)
    print("debug2")
    TriggerClientEvent('InteractSound_CL:PlayWithinDistance', -1, source, maxDistance, soundFile, soundVolume)
end)

(important that debug2 is not being printed)
This is client PLayWithinDistance:

RegisterNetEvent('LIFE_CL:Sound:PlayWithinDistance')

AddEventHandler('LIFE_CL:Sound:PlayWithinDistance', function(playerNetId, maxDistance, soundFile, soundVolume)

    local lCoords = GetEntityCoords(GetPlayerPed(-1))

    local eCoords = GetEntityCoords(GetPlayerPed(GetPlayerFromServerId(playerNetId)))

    local distIs  = Vdist(lCoords.x, lCoords.y, lCoords.z, eCoords.x, eCoords.y, eCoords.z)

    if(distIs <= maxDistance) then

        SendNUIMessage({

            transactionType     = 'playSound',

            transactionFile     = soundFile,

            transactionVolume   = soundVolume

        })

    end

end)

And here is the index.html

(I’m literally using default stuff from the interact-sound script and a custom command.)
