python zeep模块调用wcf接口取数，提示No type xxx（接口函数）in namespace None. Available elements are: NewDataSet

Question

from zeep import Client,Settings

if name == '__main__':

try:
    settings = Settings(strict=False, xml_huge_tree=True)
    client = Client('http://172.28.2.116:3638/service?wsdl',settings=settings)
    print(client.wsdl.dump())
    h2 = client.service.Get_Iteminfo_Kucount_order()
    print(h2)
except Exception as e:
    print(e)

服务器连接成功，打印的options包含一下接口：

Get_Iteminfo_Kucount_order() -> Get_Iteminfo_Kucount_orderResult: xsd:string, dt: {_value_1: ANY[], _value_2: ANY}

但是调用接口获取数据时，输出结果报错：
No element 'DocumentElement' in namespace None. Available elements are: NewDataSet

找不到原因，网上也没有查到类似情况，请大神帮忙回答下，谢谢！
