Fixed with this
---------------------------------------------------------------------------------------------------------------------------------------------
Check the new Lines 43 and 44
if weapon ~= nil
or owner:getPrimaryHandItem():getCanon() == false then

---------------------------------------------------------------------------------------------------------------------------------------------

Now error comes when you have a item on secondary hand and nothing in primary
