(0) [Exception] Actual result: -------------- Failed calling MyClass::jsonSerialize() (0) [Exception] Failed calling MyClass::jsonSerialize() (0) [Exception] Failed calling MyClass::jsonSerialize() (0) [Exception] Failed calling MyClass::jsonSerialize() (0) [Exception] Failed calling MyClass::jsonSerialize() (0) [Exception] Not implemented!
