Azure Service Bus webHttpRelayBinding using WCF REST Template causes unnecessary aspNetCompatibilityEnabled error

I am using Azure Service Bus webHttpRelayBinding using WCF REST Template but it causes unnecessary aspNetCompatibilityEnabled error even though my service-class is correctly decorated:

 [AspNetCompatibilityRequirements(RequirementsMode = AspNetCompatibilityRequirementsMode.Required)]
    [ServiceBehavior(InstanceContextMode = InstanceContextMode.PerCall)]
    [ServiceContract( Namespace = "http://samples.microsoft.com/ServiceModel/Relay/")]    
    public class InsightDataService //: Insight.WebAPI.WCFRestImplementation.IInsightDataService
    {...

My Web.Config:-

 <system.serviceModel>
    <services>
      <service name="compname.WebAPI.WCFRestImplementation.InsightDataService" behaviorConfiguration="InsightDataServiceBehavior">
        <endpoint address="https://namespacename.servicebus.windows.net/InsightDataService"
