Describe the bug
During the first stage of the Jaina Proudmoore fight in the Battle of Dazar'alor raid, when her spells/abilities root my character, an Lua Error appears.

Do you have an error log of what happened?

Did you try having DeadlyBossMods as the only enabled addon and everything else (especially something like ElvUI) disabled?

No.

Which version of DeadlyBossMods are you using?

the one released on 7/28/2024 for patch 11.0.2

Was it working in a previous version? If yes, which was the last good one?

Unsure, I did not try farming this encounter until last week, and the error appeared last time but I closed it during the fight.
