LUA Error in combat: FrameXML, edit mode, "attempt to perform arithmetic on local"

Fugz-grobbulus · November 20, 2022, 3:36pm

this exact error happens to me all the time and usually in arenas, even with all addons disabled

Aquaterra-shadowsong · November 23, 2022, 11:25am

I keep getting these errors also on multiple characters even with all addons turned off. Here is an example error of mine.

I’m seeing this error on my Balance Druid and Prot Paladin. It looks like it has something to do with the stance bar.

Lovelywazee-nagrand · November 26, 2022, 5:26pm

Still happening on multiple alts. Not sure why OP decided to mark post as “Solved” after blue reply that was clearly explaining it’s a known issue and STILL under investigation.

Sorry, fixed that. You’re right, it’s definitely not ‘solved’ yet, I just wanted to highlight their current workaround so you don’t get spammed with the error popups until they can get it fixed. <3

Aroben-frostmourne · November 27, 2022, 8:15am

It seems to be some sort of issue with the new UI in Edit Mode not being able to automatically assign new skills you learn to the hotbars when you level up. I may need to run some more tests though.

Murdi-agamaggan · November 27, 2022, 12:12pm

I’m getting a similar error. Frequently, when I enter combat, I get a lua error and my action bars become un-clickable, however pressing the hotkey still uses whatever spell was bound to it.

Bugreporter-twisting-nether · November 27, 2022, 4:40pm

Sadly the workaround does not help me because I get like 3000 of this errors at the same time (when it got triggered) so it will spam my chat with the yellow message that tells you that there are to many Lua errors.
This might be because an addon is triggering it too and I don’t blame Blizzard for that but I hope that - if it is a blizzard-bug - it can be fixed soon.

Did not see this error on my shaman btw…

Dysphoria-khazgoroth · November 28, 2022, 3:49am

Same error on this hunter. Tried with all addons disabled. The trigger seems to change. I can’t actually reproduce the bug, but when it happens, it’s often the result of flying around, landing and then engaging a mob in combat before dismounting.

a /reload fixes the problem until the next time it happens:

Arqas-proudmoore · December 4, 2022, 11:33pm

On my Mage I use Bartender, WeakAuras, etc., but also had Action Bars 2 and 5 checked. I went to Tazavesh and engaged combat, and got the usual mess of:

EditModeUtil.lua:27: attempt to perform arithmetic on local ‘offsetX’ (a nil value)
Etc.

I could exit combat using Invisibility, then immediately retrigger the above error by hitting the mobs.

Then, I then unchecked my two Action Bars in the Options. The errors stopped.

Lovelywazee-nagrand · December 7, 2022, 3:55am

Tiny bump! Any update on this?

Camillus-eldrethalas · December 12, 2022, 11:59am

I’m seeing this with no bar addon when I zone from one zone to another and engage combat. I can clear it with “/console reloadui” but that risks me dying while I’m waiting for the zone to reload. Once I reload the UI, everything is fine until I change zones.

Falco-destromath · December 12, 2022, 10:26pm

i have noticed also that when this error occurs i cant use my hotkeys without it just spamming me an error preventing me from using the key, but if i click the button with my mouse instead the same button works without the error preventing it.

Candelin-lightbringer · December 15, 2022, 6:19am

Whenever I get the error it’s always prompted by Elvui, but everyone posting about this makes me think that the addon is just displaying it. Depending on the alt I will play I will repeatedly get these lua errors in combat and have to repeatedly hide them. I’m going to disable lua errors in the console for now until they’ve released a fix.

I have 15 errors in the console right now, and all of them start with the following:

Message: Interface/FrameXML/EditModeUtil.lua:27: attempt to perform arithmetic on local 'offsetX' (a nil value)

After that, it’s a mix of EditModeManager, action bar positions, and Blizzard_ObjectiveTracker,

Napayshni-hyjal · December 15, 2022, 7:02pm

It’s definitely not an ElvUI thing, Zuvykree pointed out above that it’s a known issue that’s being worked on that isn’t addon related. =(

Bugreporter-twisting-nether · January 14, 2023, 2:22pm

Still getting this error sometimes when attacking from my dragonriding mount or when fighting against Broodkeeper Diurna. Everytime I should get the extra action-button it gives errors and the button won’t show.

Tofflemire-sulfuras · January 14, 2023, 2:58pm

i don’t think that is related to this. you likely just need to try a UI reset.

Bugreporter-twisting-nether · January 14, 2023, 3:04pm

Oh it is … its the same Lua error for

I have the exact same issue, and been having issue since day 1 of DF prepatch. I have tried reset the whole UI, reset all Cvars, resetting all addons, but still having this issue. The only fix is reload everytime a LUA error occurs, but its not a permanent fix!
