事件循环无法将承诺标记为失败，因为它已经失败

Question

根据那些指南：QUARKUS - USING ECLIPSE VERT.X和MESSAGING WITH QUARKUS AND VERT.X，我有一个非常简单的微服务，它使用sse和vert.x事件总线。 我使用react-hooks-sse进行gui渲染。 一切正常，但服务器端有很多警告：

我真的不明白这是什么意思？我必须在服务器或客户端上调整一些内容吗？

这是我的服务器代码：

@GET
    @Produces(MediaType.SERVER_SENT_EVENTS)
    @Path("/live-crossing")
    public Multi< JsonObject > liveCrossing()  {

        return eventBus.<String>consumer( "live-crossing" ).toMulti().map( a -> new JsonObject().put( "value", a.body() )  );
    }

和我的react组件

const Crossing = (props) => {


  const state = useSSE('message', {
    value: null
  });

  useEffect(() =>{
    if (state.value) {

        const dashIndex = state.value.lastIndexOf("-");
        const rawValue = state.value.substring(0, dashIndex);

        let newcrossing = [...crossing]; 
        newcrossing[newcrossing.findIndex((e) => e.startsWith(rawValue))] = state.value;
        setCrossing(newcrossing); 
  }

}, [state])

    const currentCrossingValue=props.series+"-"+props.equipment;


  return crossing.find(elem => elem.startsWith(currentCrossingValue)) != undefined ? <Switch
  checked={crossing.find(p => p.startsWith(currentCrossingValue)).endsWith("true") }
  onChange={() => handleClick(props.series, props.equipment, crossing.find(p => p.startsWith(currentCrossingValue)).endsWith("false"))}
  name="checked_CrossingValue"
  inputProps={{ 'aria-label': 'secondary checkbox' }}
/> : <React.Fragment />
  ;

  }

谢谢！
