This was the first time I encountered this kind of error after dealing with RESTful web service in couple of times. I find it hard to trace the cause of error, hope you coul
I have faced the same problem. Finally, found the issue in defining the Contract type for the return object.
I have replaced [DataMember] to [EnumMember] as described below:
[DataContract]
public enum DiscountType
{
[EnumMember]
NONE = 0,
[EnumMember]
PERCENTAGE_DISCOUNT = 1
}
This fixed my "[Fiddler] ReadResponse() failed" error which took my half day effort.
