Django反序列化程序抛出密钥错误

目前，我正在使用内置的django反序列化程序反序列化一个对象模型，我被这个KeyError异常所困扰，我无法获得关于哪个键是问题的更多信息。我不知道如何进行调试。有人有什么想法吗

注意：我不能使用内置的Django调试页面

这是我的代码的精简版本：

try:   
        # loop over deserialised objects returned from 'deserializer'
        print "serialise 123"  
        for obj in serializers.deserialize(format, data):
            print "serialise 125"  
        return True 

    except DeserializationError:
        return -1

    except Exception as e:
        print "===================="
        print type(e)
        print "********************"
        print e.args
        print "!!!!!!!!!!!!!!!!!!!!"
        print e
        return False

这是输入XML：
