django - AttributeError: 'NoneType' object has no attribute 'str' in suds -

i using suds client wsdl in our project.

i have code .

sudsclient = sudsclient(settings.wsdl_url) values = {                                     "merchantcode": settings.yp_merchant_code,                                     "merchantreference": str(reference_id),                                     "transactiontype":settings.yp_transaction_type,                                     "amount":int(charged),                                     "currencycode":client.currency,                                     "cardholdername":str(form.cleaned_data['name_on_card']),                                     "cardnumber": str(form.cleaned_data['card_number']),                                     "expirymonth":int(form.cleaned_data['exp_month']),                                     "expiryyear":int(form.cleaned_data['exp_year']),                                     "cardid":0,                                     "cardsecuritycode":str(form.cleaned_data['security_code']),                                     "customeraccountnumber":"",                                     "billnumber":0,                                     "cardholderemail":str(form.cleaned_data['email']),                                     "clientipaddress":get_ip,                                     "notes":"ok",                                             } response = sudsclient.service.onlinetransaction(**values) 

when run program got error:

exception type: attributeerror exception value:     'nonetype' object has no attribute 'str' exception location: /usr/local/lib/python2.7/dist-packages/suds/sax/document.py in str, line 48 

i sure code in local , test same.

i think problem in suds, don't have idea on how solve it.

i really2x don't know why got error. got same error in local , production. btw, when separate code , try run. runs ok.

sudstest.py

#!/usr/bin/env python import os suds.client import client abo  wsdl = 'directconnect.production.wsdl'  #def test_api(): url = 'file://' + os.path.join(os.path.abspath(os.path.dirname(__file__)), wsdl) print url client = abo(url)  data = {     'merchantcode': 'hello',     'merchantreference':  '3252',     'transactiontype': 20,     'amount': 10,     'currencycode': 'usd',     'cardholdername': 'raul o reveche',     'cardnumber': 4005550000000001,     'expirymonth': 5,     'expiryyear': 2013,     'cardid': 0,     'cardsecuritycode': 400,     'customeraccountnumber': '',     'billnumber': 0,     'cardholderemail': 'development@yespayments.com.ph',     'clientipaddress': 'http://127.0.0.1:8000/',     'notes': 'this test', }  print data result = client.service.onlinetransaction(**data) print result.responsedescription 

the exception caued none value returned self.root, following in suds.sax.document,

def root(self):      if len(self.children):          return self.children[0]      else:          return none  

so seems caused lacking data fields. replay exact data fill on test server, on local machine again might help. check django settings on test server make sure similar local settings.
