You need to register events before you can trigger them:

for k, v in pairs(Eavu) do
 frame:RegisterEvent(k); -- Register all events for which handlers have been defined
end
 
frame:SetScript("OnEvent", function(self, event, ...)
 Eavu[event](self, ...); -- call one of the functions above
end)

I think coding when you're sick is a bad idea, i tried do "programming" once i was drunk, thex next day was a massive omg wtf rollback.

However that table should contain the events you want to register:

local Events = {
 [1] = "ADDON_LOADED",
 [2] = "COMBAT_LOG_EVENT_UNFILTERED",
 [3] = "ETCETC"
}
 
for k, v in pairs(Events) do
 frame:RegisterEvent(v); -- Register all events for which handlers have been defined
end

Also if you use the in pairs loop then you need to register it's v part not the k. (But it depends how your table looks like.)
