NodeJS Bolt-js slack应用程序Jenkins PM2部署EADDRINUSE问题

我用bolt-js，node.js和slack api做了一个slack应用。
我已经使用PM2设置了一个Jenkins CI/CD管道来将node.js部署到AWS EC2，但是在pm2重新加载步骤中遇到了一些问题。
EC2示例中有两个核心，因此当我在PM2集群模式下运行它时，有两次运行。
以下是我的ecosystem.config.js：

module.exports = {
  apps: [{
  name: 'project-name',
  cwd: './project-path',
  script: 'npm',
  args: 'start',
  instances: 0,
  exec_mode: 'cluster_mode' 
  }]

字符串
当我运行pm2 start ecosystem.config.js命令时，它运行得很好-没有port already in use错误。但是当我用pm2 reload <appname>重新加载pm2时，显示以下错误：

Error: listen EADDRINUSE: address already in use :::3000
    at Server.setupListenHandle [as _listen2] (node:net:1740:16)
    at listenInCluster (node:net:1788:12)
    at Server.listen (node:net:1876:7)

  errno: -98,

  address: '::',
  port: 3000

它说我的端口3000已经在使用中，并自行重新加载三次。
当集群从集群0切换到集群1时，多次重新加载是成功的-它完成了自己的工作，并在多次重新加载后成功部署了更新的代码，如下所示：

[nodemon] app crashed - waiting for file changes before starting...

2023-09-13T15:40:12: PM2 log: Stopping app:project-name id:_old_0
2023-09-13T15:40:12: PM2 log: App name:project-name id:_old_0 disconnected
2023-09-13T15:40:12: PM2 log: App [project-name:_old_0] exited with code [0] via signal [SIGINT]
2023-09-13T15:40:12: PM2 log: pid=13051 msg=process killed
2023-09-13T15:40:12: PM2 log: App [project-name:1] starting in -cluster mode-
2023-09-13T15:40:12: PM2 log: App [project-name:1] online

然而，当集群从集群1切换到集群0时，它只是停留在应用程序崩溃的消息上，就像这样：[nodemon] app crashed - waiting for file changes before starting...并且新的集群没有启动。

[nodemon] app crashed - waiting for file changes before starting...

2023-09-13T15:32:41: PM2 log: Stopping app:project-name id:_old_1
2023-09-13T15:32:41: PM2 log: App name:project-name id:_old_1 disconnected
2023-09-13T15:32:41: PM2 log: App [project-name :_old_1] exited with code [0] via signal [SIGINT]
2023-09-13T15:32:41: PM2 log: pid=12638 msg=process killed

为什么会这样？
