   比较奇怪,你可以看下服务端的日志。 详细日志可以参考下 `RestCodec` 里面如何打印的, 可能没打全,需要个配置开关。 
   
   ```
         } catch (Exception e) {
           // Avoid information leak of user input, and add option for debug 
use.
           String message = String
               .format("Parameter is not valid for operation [%s]. Parameter is 
[%s]. Processor is [%s].",
                   
restOperation.getOperationMeta().getMicroserviceQualifiedName(),
                   param.getParamName(),
                   param.getParamProcessor().getProcessorType());
           if (DynamicPropertyFactory.getInstance().getBooleanProperty(
               RestConst.PRINT_CODEC_ERROR_MESSGAGE, false).get()) {
             LOG.error(message, e);
           } else {
             LOG.error("{} Add {}=true to print the details.", message, 
RestConst.PRINT_CODEC_ERROR_MESSGAGE);
           }
           throw new InvocationException(Status.BAD_REQUEST, message);
         }
       }
   ```
