No longer working with latest 1.15 patch

[achinhorn]

Disclaimer: I'm but a simple user -- I have zero experience with LUA and would not consider myself a programmer.

Which software were you running?

• Addon version name: Wow Classic 10.1.8
• Client used: [e.g. Vanilla 1.14.4, Retail PTR x.x.x, etc]
  1.15

Have you read the changelog?
Nope.

Please describe the bug.
I haven't changed anything except update WOW and it isn't working any longer with the latest patch.

• It doesn't auto-sell any longer
• It doesn't auto-repair any longer
• The extra scrap gui options at the vendor are now not working

The only thing that "works" is the trash icon is correctly marking trash items in my inventory, but all of the main vendor interaction features are not working.

Please describe how to reproduce it.
Update WOW to the latest 1.15 patch.

Any Screenshots?
If applicable, please add screenshots to help explain your problem.

Error Logs are Important!
Type /console scriptErrors 1 in the chat and reload the game. If an error window appears when reproducing the bug, please write here the first message (labelled 1/Many) that appeared. ⚠️ By default, the last error message is shown, not the first! You need to navigate back to the first error.

Using the scriptErrors, I didn't get any errors on reload, but this is what I get when I talk to a vendor:
