[Help] Client event not triggering

Hello everyone, I am planning to develop a custom mod, but I am stuck with client events not triggering.

Here is a sample code where I can’t get the “response” event triggering :

server.lua

RegisterServerEvent('request')
RegisterServerEvent('clientLog');

AddEventHandler('request', function()
    RconPrint('request received')
    TriggerClientEvent('response', source)
end)

AddEventHandler('clientLog', function(str)
    RconPrint('clientLog => ' .. str)
end)

client.lua

RegisterNetEvent('response')

AddEventHandler('response', function()
    TriggerServerEvent('clientLog', 'response triggered');
end)

TriggerServerEvent('request')

What am I doing wrong ?

Same here
