OpenHarmony应用开发时同时启动多个不同的worker出问题

【问题描述】
问题现象和发生的背景
我定义了两种不同的worker——TimeWorker和RaftWorker，RaftWorker需要向RaftWorker请求计时结果，同时UI线程需要向RaftWorker发送数据请求，进行一致性处理，但是在运行时出现bug。

相关的代码，截图，日志信息
RaftWorker.ets的代码：
import worker, { ThreadWorkerGlobalScope, MessageEvents, ErrorEvent } from '@ohos.worker';
import distributedKVStore from '@ohos.data.distributedKVStore';
import { GlobalContext } from '@ohos/dataorm';
import { raftStateMachine, Operation } from '../raft/RaftStateMachine';

const workerPort: ThreadWorkerGlobalScope = worker.workerPort;

const kvStore: distributedKVStore.SingleKVStore = GlobalContext.getContext().getValue('kVStore') as distributedKVStore.SingleKVStore

const applyLog = (op: Operation): void => {
  kvStore.put(op.key, op.val)
}

export const raftServer = new raftStateMachine(applyLog)

// const raftStateMachine: raftStateMachine = new raftStateMachine(applyLog)

/**
* Defines the event handler to be called when the worker thread receives a message sent by the host thread.
* The event handler is executed in the worker thread.
*
* @param e message data
*/
workerPort.onmessage = (e: MessageEvents): void => {
  raftServer.serve()
}

/**
* Defines the event handler to be called when the worker receives a message that cannot be deserialized.
* The event handler is executed in the worker thread.
*
* @param e message data
*/
workerPort.onmessageerror = (e: MessageEvents): void => {
}

/**
* Defines the event handler to be called when an exception occurs during worker execution.
* The event handler is executed in the worker thread.
*
* @param e error message
*/
workerPort.onerror = (e: ErrorEvent): void => {
}

TimeWorker.ts的代码如下：
import worker, { ThreadWorkerGlobalScope, MessageEvents, ErrorEvent } from '@ohos.worker';
import { CANCEL_TIMER, TIMER_NORMAL_END } from '../utils/ConstData';

const workerPort: ThreadWorkerGlobalScope = worker.workerPort;
let isTimerSet: boolean = false
/**
* Defines the event handler to be called when the worker thread receives a message sent by the host thread.
* The event handler is executed in the worker thread.
*
* @param e message data
*/
// 接受主线程发来的计时请求，开始启动选举计时器
workerPort.onmessage = function (e: MessageEvents) {
  let data: number = e.data
  if (data == CANCEL_TIMER) {
    isTimerSet = false
} else {
    isTimerSet = true
setTimeout(()=>{
      console.log(data + " ms timeout");
    }, data)
    if (isTimerSet) {
      workerPort.postMessage(TIMER_NORMAL_END)
    }
  }
}

/**
* Defines the event handler to be called when the worker receives a message that cannot be deserialized.
* The event handler is executed in the worker thread.
*
* @param e message data
*/
workerPort.onmessageerror = function (e: MessageEvents) {
  console.log(e.data)
}

/**
* Defines the event handler to be called when an exception occurs during worker execution.
* The event handler is executed in the worker thread.
*
* @param e error message
*/
workerPort.onerror = function (e: ErrorEvent) {
  console.log(e.message)
}

我尝试过的解决方法和结果
暂时没有解决的思路，也没找到相关的代码示例

我想要达到的结果
我要同时能够启动两个不同的worker线程（分别运行不同的代码逻辑），后面还可能会启动更多的worker

代码看起来可能有问题，方便附上最小能复现问题的demo么？ 有demo才好判断。
