This is a bug that blizzard has to fix (we've been told they're working on hotfixing it, hopefully we'll see it early this week)

[rakkarage]

disabling the three tooltip options fixes it so does this pull request

I appreciate the PR and bug reports
the last errors you mentioned isn't something I ran into when doing a few keys, I'll look into them

I don't have time to test anything until tomorrow however

[rakkarage]

thanks, i think they may be obscured by the first issue...
i did not see/isolate them until the first issue was resolved.
the first issue can be replicated in seconds at target dummy by entering combat and waving mouse around buttons and frames and target
those other two show up half way thru dungeon
i may have messed up formatting (semicolon preference)/double commit pr, feel free to just use them as proof of concepts

[Numynum]

I did some testing, and your PR didn't fix things for me, whether you do things in combat or not doesn't make a difference to this error
in fact, this error can happen with a simple /run TooltipDataProcessor.AddLinePostCall(Enum.TooltipDataType.Item, function() end)
blizzard said they're likely to hotfix this in the upcoming few days

the 2 errors from your later message are resolved (one was caused by a guild message during a m+ run/pvp match/raid fight), the other I'm not quite sure how that's even possible, perhaps due to some mind control or something 🤷‍♂️

[rakkarage]

/run TooltipDataProcessor.AddLinePostCall(Enum.TooltipDataType.Item, function() end)

this does nothing... no error, nothing... if it causes an error for you maybe from another addons?

this is the error i am talking about...

it continues to be easily replicatable...
it can be fixed by:

• disabling whole addon
• disabling "Show Score on Mythic Keystone" option (i narrowed it down further, the other two tooltip options are fine)
• change showScoreOnKeystoneTooltip.lua code to use AddTooltipPostCall instead of AddLinePostCall

i understand that blizzard is going to fix "some things" but i don't think this is one of them

        TooltipDataProcessor.AddTooltipPostCall(Enum.TooltipDataType.Item, function(tooltip) Module:TooltipPostCall(tooltip) end);

function Module:TooltipPostCall(tooltip)
    if not self.enabled then return; end
    if not tooltip or not tooltip.GetItem then return end

    local _, itemLink = tooltip:GetItem();
    if not itemLink then return; end
    
    -- Check if this is a keystone tooltip by looking for the Mythic+ Power Level line
    local foundKeystone = false
    local tooltipName = tooltip:GetName()
    
    for i = 1, tooltip:NumLines() do
        local line = _G[tooltipName .. "TextLeft" .. i]
        if line and line:GetText() then
            local text = line:GetText()
            if text and string.find(text, CHALLENGE_MODE_ITEM_POWER_LEVEL) then
                foundKeystone = true
                break
            end
        end
    end
    
    if not foundKeystone then return end

    self:HandleHyperlink(tooltip, itemLink);
end

i do not have a mythic+ keystone in bag or at all currently, and am not mousing over a mythic+ keystone when triggering issue.

thanks

/run TooltipDataProcessor.AddLinePostCall(Enum.TooltipDataType.Item, function() end)
get in combat, and hover over an aura tooltip -> error
that's with 0 addons

blizzard is aware, and will fix it (that's not a hunch, it's confirmed)

using a TooltipPostCal instead of a LinePostCall would be a temporary fix for a bit, but it'll be fixed soon enough anyway

and checking for combatlockdown makes no difference
