Solve the following python programming problem given the following code:
def _bsp_traverse(node, callback, userData, func) : 
    def node_converter(cnode, data) : 
        node = Bsp (cnode) 
        return callback (node, data) 
cbk_func = BSP_CBK_FUNC (node_converter) 
    func (node_converter.p, cbk_func, userData) 

    
    

    Fix the buggy line: func (node_converter.p, cbk_func, userData)
