Access issue related to Odata in iOS native code

Hi All,

I am developing one native iOS app using smp , relay and sap netweaver server.

I have created the Odata service using RFC and the service is working fine in all browsers and rest client.

But when I am trying to access the service from my iOS code it is giving error that SUPJSONException : expected string, found. Internal server error.

I checked my server logs on SMP side and it is saying that IOException caught In Handle method of GWProxy.

I am able to access the service from netweaver server , relay server and smp server.

Please suggest some way to resolve this issue.

With Regards
