Reactjs 自定义插件实现节js存在问题

我已经试着把这一节寄给你来改变房间的主题

<iq from='hag66@shakespeare.lit/pda'
    id='subject1'
    to='coven@muclight.shakespeare.lit'
    type='set'>
    <query xmlns='urn:xmpp:muclight:0#configuration'>
        <subject>To be or not to be?</subject>
    </query>
</iq

import { Agent, JXT } from 'stanza';
import { IQType } from 'stanza/Constants';




export interface MyStanza {
 
  subject: string;
}

declare module 'stanza' {
  export interface Agent {
      sendMyStanza(jid: string, data: string): void;
  }
  export interface AgentEvents {
      mystanza: IQType & { mystanza: MyStanza };
  }
  namespace Stanzas {
      export interface IQType {
          mystanza?: MyStanza;
      }
  }
}

export default function (client: Agent, stanzas: JXT.Registry) {
  const NS = 'urn:xmpp:muclight:0#configuration';
  stanzas.define({
   element: 'query',
   namespace: NS,
      fields: {
         
         subject: JXT.childText(null, 'subject'),
      },
  });


  client.sendMyStanza = (jid: string, data: string)=> {
       client.sendIQ({
          id:'subject1',
          type:"set",
          to:jid,
          mystanza: {
           subject:data
          }
      });
  };

  client.on('iq', iq => {
     console.log(iq)
    
      
  });
};

APP.js

我导出自定义插件并在use effect组件中使用它。。但是我得到了错误的请求

 import Roomsubject  from './roomsubject.tsx';
    
function App() {
useEffect(() => {

    const client = XMPP.createClient({
      jid: "92333@chat.com",
      password: "123456",
      transports: {
        websocket: "ws://chat.com:1234/ws-xmpp",

      }
    });

  client.use(Roomsubject);
  client.on('session:started', async() => {
      try {
        await  client.sendMyStanza("644727e2-3600@muclight.chat..com","test")
       
       } catch (error) {
         alert(error)
       }
  });
     client.connect();


  }, []);

正在发送的IQ

<iq xmlns="jabber:client" id="29a7e0d6-26ae-4a16-bd1b-e1b9f6aae446" type="set" to="644727e2-3600-@muclight.chat.com"/>

响应
