Unable to resolve type #943

Hi, I'm trying to write a Powerschool API and I'm getting this error:

Traceback (most recent call last):

As you can see from the code, I've tried turning strict mode off and using every setting available to get it working. Despite turning off strict mode and requesting the raw XML response, it still tries parsing it then complains.

from requests.auth import HTTPDigestAuth
from requests import Session
from zeep import Client, exceptions
from zeep.transports import Transport
from zeep.settings import Settings

class PowerschoolAPI:
    def __init__(self, url, api_username:str = 'pearson', api_password:str = 'm0bApP5'):
        self.url_ = url
        self.session_ = Session()
        self.session_.auth = HTTPDigestAuth(api_username, api_password)
        self.api_username_ = api_username
        self.api_password_ = api_password
        self.setup()

    def setup(self):
        public_portal_service_url = self.url_ + '/pearson-rest/services/PublicPortalServiceJSON'
        settings = Settings(strict=False, raw_response=True, forbid_dtd=False, forbid_entities=False, forbid_external=False, xsd_ignore_sequence_order=True)
        self.client_ = Client(wsdl=public_portal_service_url + '?wsdl', transport=Transport(session=self.session_), settings=settings)

    def login(self, username, password):
        print(self.client_.service.loginToPublicPortal(username, password))
        #print(self.client_.loginToPublicPortal(username, password))

    url_ = None
    session_ = None
    api_username_ = None
    api_password_ = None
    client_ = None

api = powerschoolapi.PowerschoolAPI('http://sales.powerschool.com', 'pearson', 'm0bApP5')

This exact same error has happened with two different schools' Powerschool SOAP APIs. The WSDL is here. Use 'pearson' as the username and 'm0bApP5' for the password (this is the default credentials, I'm not exposing anything that isn't publicly available). I'm using the latest zeep version. Thanks!

I'm having the exact same error with this WSDL file, and I've no idea what the error means. The file itself seems to be valid, at least per some validators I've found:

http://desarrollo.urbano.com.ar/webservice/?wsdl

Have you managed to get this working somehow?

It is still relevant
