Have just started getting this on a subset of json format calls. Kind of strange, I don’t think it came directly after an upgrade of ServiceStack or Xamarin. Does not seem to affect other formats e.g. html or xml. Does not affect all calls. This particular api call doesn’t do much, just plays back the log4net log as text. It outputs most of the api response and then spews out the below. service implementation is below
I am running latest servicestack and xamarin bits.
