hooksecurefunc issue, current addon InFlight

[Uitat]

well as a newly minted maintainer of this addon there are a few bits and pieces i don't understand, that happen to be broken

there was some change that happened during the update that messed with at a minimum this line of code
i have searched for this GossipTitleButton_OnClick but i am comming up empty handed on info
line76

hooksecurefunc("GossipTitleButton_OnClick", function(this, button)

the full chunk
lines 76 to 105

hooksecurefunc("GossipTitleButton_OnClick", function(this, button)
        if this.type ~= "Gossip" then
            return
        end
 
        local subzone = GetMinimapZoneText()
        local tsz = t[subzone]
        if not tsz then
            return
        end
 
        local text = this:GetText()
        if not text or text == "" then
            return
        end
 
        local source, destination
        for _, sz in ipairs(tsz) do
            if strfind(text, sz.find, 1, true) then
                source = sz.s
                destination = sz.d
                break
            end
        end
 
        if source and destination and LoadInFlight() then
            self:StartMiscFlight(source, destination)
        end
    end)

It's now a template that uses a Mixin. You will have to find the button(s) that inherit the template

<Button name="GossipTitleButtonTemplate" virtual="true" mixin="GossipSharedTitleButtonMixin" hidden="false">

There are also templates that inherit that template so, depending on what you need, it might be a bit of a hunt.

<Button name="GossipTitleActiveQuestButtonTemplate" virtual="true" inherits="GossipTitleButtonTemplate" mixin="GossipActiveQuestButtonMixin">
