Here is two LUA error I got today:

Hey,

This is a false positive - the problem is, that if some addon breaks something, and another tries to call it (or call something that calls it), it will fail, and the error will point to that addon, instead of the one that broke it.
The SetPassThroughButtons function is not used anywhere in this addon, even though the error points to it trying to call that function - this is the exact case, where something breaks something, and later down the line, something else trips over it 🙂

Unfortunately, there is no way to see, what caused the problem in the first case.
Can you please try and see if you can reproduce the issue with only this addon and BugGrabber/BugSack loaded - if so, please provide the error message from there, and reopen the ticket 🙂
