any way to get a fix for this it happens all the time and there are not pet battles in Classic wow

I think you've installed the retail version of this addon. Try downloading the Classic version.
v4-classic -- https://github.com/funkydude/SexyMap/tree/v4-classic

I have checked and it is the classic version from twitch
that link you put in there if you go into the SexyMap.lua and look at link 587 it talk about

mod.frame:RegisterEvent("PET_BATTLE_OPENING_START")

Check out the version I linked above. That's the one I had installed and it only has 489 lines in the SexyMap.lua file. I've heard all kind of things about the twitch app installing the wrong version of add-ons. I just download them direct from curseforge and put them in the addon folder myself.

Closing as invalid. As has already been said, you're using the retail version and not the classic version. Uninstall, then install it fresh or use Twitch to manage it for you.
