An event handler that is called with the error Exception if a Json Process method fails. You can override this method to log errors or otherwise capture the error exception.

Unlike the page OnError() handler, this handler method doesn't generate any output - it only provides a mechanism for capturing the error and potentially logging it.

Note: The wwRestProcess::OnError() handler never fires and should not be used, because all processing is handled internally by wwJsonService::CallMethod() processing and its own exception wrapping that captures all error information. OnError() receives that exceptino on failed requests.

OnJsonError() only captures the exception but doesn't perform any other operations to modify the output - it should not generate any output.
