Unable to create message after passing dict

[waywayup1234]

No idea what is happening, I passed in the dict just as the wsdl.dump() specified, keeping getting the typeError

The version of zeep : v4.0.0 The WSDL you are using: https://mitre-cpt.costpointenterprise.com/cpweb/webservices/cpwwsgenericmoduleWS?wsdl An example script (please see below)

    session = Session()
    session.verify = False
    transport = Transport(session=session)
    settings = Settings(xml_huge_tree=True)

    try:
        client = Client(wsdlurl, settings=settings, transport=transport)
    payload = {'systemName': '1', 'companyId': '1', 'document': '1'}
   # payload with name argument per the zeep dump
    # node = client.create_message(client.service, 'cpwwsgenericimport', systemName='1', companyId='a', document='o')
   # payload with dict
    node = client.create_message(client.service, 'cpwwsgenericimport', **payload)
    tree = let.ElementTree(node)
    tree.write('env.xml', pretty_print=True)

Got error on **binding_options
