Describe the bug
Lua Error when opening a vendor, autosell does not function. worth noting that items can still be set as junk or useful and still have the gray border, they just do not sell when a vendor is visited. I only noticed this in the last few days, I have tried uninstalling and rolling back to 9.0.6 but it did not resolve the issue.

To Reproduce
Steps to reproduce the behaviour:

• open any vendor window
• observe lua error

Expected behaviour

• items marked as junk will autosell.

It is no longer doing it, it seems to have been triggered by a specific item I had in my inventory? But I have no idea what it was.

I figured it out, when the [Idol of the Avian Heart] from Karazhan is in my bag, it throws the error

ty for figuring it out! yup looks like having any druid idol in your bags breaks it, i had the idol of the emerald queen

Weirdly it only seems to be resto idols. Harold's rejuvenating brooch does the same thing, but all the feral idols I usually have (I main bear), I haven't had any issue with. I have the idol of the claw and the idol of brutality with me all the time and no issue.

Have no way to recreate this. God knows I tried.
