Start with the reported TriRpcStatus.java:214 failure and trace the named GatewayFacade.index call through GatewayServiceImpl.java:20 and GatewayController.java:25, then compare the provider and consumer service declarations shown in the report. There is no test named in the issue; done would require a reproducible diagnosis explaining why the registered method is not available to the consumer.
