Attempt to call a nil value when xpcall doesn't return an error

[Ryguy903]

When runGame() completes without any errors, the error function will still run and say attempt to call a nil value. I tested this by just calling runGame() with no xpcall and I didn’t get any errors.

local function warnWithTracebackOnError()
	xpcall(runGame(), function(err)
		warn(tostring(err) .. "\n" .. debug.traceback())
        --other code
	end)
end
warnWithTracebackOnError()

You are calling the function within the argument. You just need to pass the identifier.

xpcall(runGame, ...)
