Error on console! OXIDE

Web request callback raised an exception (InvalidCastException: Null object cannot be converted to a value type.) at System.Convert.ChangeType (System.Object value, System.Type conversionType, System.IFormatProvider provider) [0x00019] in <f98723dd4586469db5213ec59da723ca>:0 at Newtonsoft.Json.Serialization.JsonSerializerInternalReader.EnsureType (Newtonsoft.Json.JsonReader reader, System.Object value, System.Globalization.CultureInfo culture, Newtonsoft.Json.Serialization.JsonContract contract, System.Type targetType) [0x0007c] in <271c58b7a8684db5a2c92be17a81f252>:0

is this still an issue? what are you doing when you get this error? is it on startup, random, all the time?

Changed Status from Pending to Work in Progress
