AttributeError：“NoneType”对象在 suds 中没有属性“str”

我在我们的项目中使用 WSDL 的 suds 客户端。

我有这个代码。

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)

当我运行我的程序时，我收到此错误：

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

我确信我本地和测试中的代码是相同的。

我认为问题在于suds，但我不知道如何解决它。

有谁可以帮助我解决我的情况吗？ 提前致谢 ..

我真的不知道为什么会出现这个错误。 现在我在本地和生产中遇到了同样的错误。 顺便说一句，当我分离代码并尝试运行时。运行正常。

臭虫存在于泡沫中。 @okm 很接近，但问题确实在于Document.__str__。然而，该错误仅在使用 django-debug-toolbar 时才会暴露，因为日志记录面板显示已记录的所有消息。这会触发泡沫错误。
