Solve the following python programming problem given the following code:
def bb_query(self, bb, layers = (- 1), group = 0) : 
    "Perform a fast rectangle query on the space.
        
        Only the shape's bounding boxes are checked for overlap, not their 
        full shape. Returns a list of shapes.
        " 
    self.__query_hits = [] 
    def cf(_shape, data) : 
        shape = self._get_shape (_shape) 
        self.__query_hits.append (shape) 
f = cp.cpSpaceBBQueryFunc (cf) 
    cp.cpSpaceBBQuery (self._space, bb._bb, layers, f, f, None) 
    return self.__query_hits 

    
    

    Fix the buggy line: cp.cpSpaceBBQuery (self._space, bb._bb, layers, f, f, None)
