WowAce

Hi,

I am getting a recurring Lua error from GatherMate2 in Retail WoW, specifically inside Delves.

Core error:
Interface/AddOns/GatherMate2/GatherMate2.lua:527: attempted to index a table that cannot be indexed with secret keys

Environment:
- WoW: Retail 12.0.5
- Build: 67314
- Interface: 120005
- Addon: GatherMate2

Observed cases:

1) Opening the reward chest at the end of a Delve
Message: Interface/AddOns/GatherMate2/GatherMate2.lua:527: attempted to index a table that cannot be indexed with secret keys
Time: Fri May 1 22:45:17 2026

2) Killing a mob inside a Delve

[Interface/AddOns/BattlePetCompletionist/Libs/AceEvent-3.0/AceEvent-3.0.lua]:120: in function <...>

Expected result:
No Lua error should occur when opening the final Delve chest or when killing a mob inside a Delve.

Actual result:
GatherMate2 throws a secret-key error in GetIDForNode at GatherMate2.lua:527.

Additional context:
The callback chain is not always the same - once it went through RareScanner/AskMrRobot, another time through BattlePetCompletionist - but the actual failing function is always GatherMate2.lua:527 / GetIDForNode.

This makes it look like GatherMate2 is trying to identify a node/container/unit-related object in Delves whose data is protected with secret keys in current Retail.

Thanks for taking a look.
