Python Zeep中格式良好的文档中需要根元素

Question

试图使用Python的Zeep包调用专有服务，因为它是专有的，我不能给出WSDL URL，我们必须签署协议

from zeep.wsse.username import UsernameToken
from zeep import Client

client = Client('http://IP/<PATH>?<filename>.wsdl', wsse=UsernameToken('Username', 'Password'))


client.service.serviceName(param={'param': 1}, param2={'param2': 2}, param3={'param3': 3})

Fault: org.xml.sax.SAXParseException: The root element is required in a well-formed document. Message being parsed:
