当前行为：

wasabi::Resolver::HTTPError: Error: 500 for url http://108.60.219.77:6543/BusinessServices/Billing/DiscountsAndPromotions/Shahid/Service/Service.serviceagent/ShahidPortTypeEndpoint1 /home/clustox/.rvm/gems/ruby-2.7.1/gems/wasabi-3.6.1/lib/wasabi/resolver.rb:47:in load_from_remote' /home/clustox/.rvm/gems/ruby-2.7.1/gems/wasabi-3.6.1/lib/wasabi/resolver.rb:35:in resolve' /home/clustox/.rvm/gems/ruby-2.7.1/gems/wasabi-3.6.1/lib/wasabi/document.rb:144:in xml' /home/clustox/.rvm/gems/ruby-2.7.1/gems/wasabi-3.6.1/lib/wasabi/document.rb:162:in parse' /home/clustox/.rvm/gems/ruby-2.7.1/gems/wasabi-3.6.1/lib/wasabi/document.rb:149:in parser' /home/clustox/.rvm/gems/ruby-2.7.1/gems/wasabi-3.6.1/lib/wasabi/document.rb:66:in soap_actions' /home/clustox/.rvm/gems/ruby-2.7.1/gems/savon-2.12.1/lib/savon/client.rb:28:in operations' /home/clustox/Desktop/Rworkplace/soapify/lib/tasks/call_wsdl_operations.rake:17:in 块（2级）在' /home/clustox/.rvm/gems/ruby-2.7.1/gems/rake-13.0.6/exe/rake:27:in <top (required)>' /home/clustox/.rvm/gems/ruby-2.7.1/bin/ruby_executable_hooks:24:in eval' /home/clustox/.rvm/gems/ruby-2.7.1/bin/ruby_executable_hooks:24:in `'

重现当前行为的步骤： client = Savon.client(wsdl:"http://108.60.219.77:6543/BusinessServices/Billing/discountsAndPromotions/Shahid/Service/Service.serviceagent/ShahidPortTypeEndpoint1")

客户端操作

预期行为：

client.operations 应该返回 WSDL 操作
