Hi,

I've created a Endpoints Webservice instance pointing to a wsdl and can successfully connect. I've also created a basic SmartObject in order to test the service. However, when I try execute the SmartObject method, I get a HTTP "417 Expectation Failed" error straight away. Having done a little reading, I tried to amend the web config so as not to send the Expect: 100-Continue header, but this has seemed to make no difference.

Has anyone else run into this issue before? Any ideas?
