Solve the following python programming problem given the following code:
@ classmethod 
def define_tables(cls, metadata) : 
    global Table1, Table1B, Table2, Table3, Data 
    table1 = Table ('table1', metadata, Column ('id', Integer, primary_key = True, test_needs_autoincrement = True), Column ('related_id', Integer, ForeignKey ('table1.id'), nullable = True), Column ('type', String (30)), Column ('name', String (30))) 
    table2 = Table ('table2', metadata, Column ('id', Integer, ForeignKey ('table1.id'), primary_key = True)) 
    table3 = Table ('table3', metadata, Column ('id', Integer, ForeignKey ('table1.id'), primary_key = True)) 
    data = Table ('data', metadata, Column ('id', Integer, primary_key = True, test_needs_autoincrement = True), Column ('node_id', Integer, ForeignKey ('table1.id')), Column ('data', String (30))) 
    join = table1.outerjoin (table2).outerjoin (table3).alias ('pjoin') 
    class Table1 (object) : 
        def __init__(self, name, data = None) : 
            self.name = name 
            if (data is not None) : 
                self.data = data 
def __repr__(self) : 
            return ('%s(%s, %s, %s)' % (self.__class__.__name__, self.id, repr (str (self.name)), repr (self.data))) 
class Table1B (Table1) : 
        pass 
class Table2 (Table1) : 
        pass 
class Table3 (Table1) : 
        pass 
class Data (object) : 
        def __init__(self, data) : 
            self.data = data 
def __repr__(self) : 
            return ('%s(%s, %s)' % (self.__class__.__name__, self.id, repr (str (self.data)))) 
try : 
        table1_mapper = mapper (Table1, table1, select_table = join, polymorphic_on = table1.c.type, polymorphic_identity = 'table1', properties = { 
            'nxt' : relationship (Table1, backref = backref ('prev', foreignkey = join.c.id, uselist = False), uselist = False, primaryjoin = (join.c.id == join.c.related_id)), 
            'data' : relationship (mapper (Data, data)), 
}) 
        configure_mappers () 
        assert False 
except : 
        assert True 
        clear_mappers () 
table1_mapper = mapper (Table1, table1,...

    
    

    Fix the buggy line: 'data' : relationship (mapper (Data, Table1), lazy = 'joined', order_by = data.c.id) ,

#Here is Python program to fix the buggy line: 'data' : relationship (mapper (Data, Table1), lazy = 'joined', order_by = data.

'data' : relationship (mapper (Data, data), lazy = 'joined', order_by = data.c.id) ,
