Describe the bug

This error happens when I open my bags for the first time after logging in. AdiBags UI appears but also an error popup.

Steps to reproduce

1. log in onto a character (doesn't happen after /reloadui, only after logging in)
2. open bags -> the error happens

Verification

• [X] I have disabled all other addons and made sure this bug is triggered only with AdiBags enabled
