OData gives result only after making a web API request

I have created an Odata in web Api 2

I am adding routes like 

config.MapODataServiceRoute(
            routeName: "ODataRoute",
            routePrefix: "odata",
            model: GetModel()
        );

config.Routes.MapHttpRoute(
            name: "DefaultApi",
            routeTemplate: "api/{controller}/{id}",
            defaults: new { id = RouteParameter.Optional }
        );

I am getting a strange result.

If I hit the OData service first (after a building/publishing) it is showing the below image. enter image description here

But if I hit an api request first and making the OData request next,

then I am getting the expected JSON.

In short an OData request works only after making an API request.

Can anyone say what would be reason for this behavior?

Order matters. Try moving the OData config after the Web API config:

config.Routes.MapHttpRoute(
        name: "DefaultApi",
        routeTemplate: "api/{controller}/{id}",
        defaults: new { id = RouteParameter.Optional }
    ); 

config.MapODataServiceRoute(
        routeName: "ODataRoute",
        routePrefix: "odata",
        model: GetModel()
    );

If you don't have any regular Web API controllers, eliminate the call to MapHttpRoute entirely.
