Lua Error

Lua Error popup

Lua Error is a popup window that appears when an addon or the base game interface encounters a coding error. It helps to identify the addon that failed, where in the code that it failed, and a brief description of the error.

This window will popup if scriptErrors is enabled. Alternatively, community-made addons like BugSack (and BugGrabber), Swatter, or others can catch and process these errors.

Notes

• This window commonly makes an appearance after a pre-patch or in the beta client as they introduce breaking changes to the API that addons relied on.
