While working on Votan's Fish Fillet I found out the following:
If a hooked function (or a sub-call) using a private/protected function like "UseItem" is not the very last call by using
return, this message is coming.
e.g.
fails:
function NewFunction(...)
-- action
hookedFunction(...)
end
working:
function NewFunction(...)
-- action
return hookedFunction(...)
end
Even if the hooked function has no return values. But this causes the error message reproducable.
In my case, it was hooking the context-menu. (right-click)
If the error is random, it can be caused by adding the wrong fragment type to HUD_SCENE (from any addon)
