When you change the WCF SOAP services to REST, the whole mindset of error reporting and handling changes.

In SOAP, faults are part of your contract. In REST, they simply become codes that you output in the HTTP response code and description.

Here is a catch snippet:

catch (Exception e)
{
    Trace.WriteLine(e.ToString());

    OutgoingWebResponseContext response = WebOperationContext.Current.OutgoingResponse;
    response.StatusCode = System.Net.HttpStatusCode.UnsupportedMediaType; // or anything you want
    response.StatusDescription = e.Message;
    return null; // I was returning a class
}

So I would suggest you create a helper code which creates relevant error codes for you and put in the response.
