无法建立因未捕获异常而断开的 websocket 连接：错误 [ERR_IPC_CHANNEL_CLOSED]：通道已关闭

如何解决无法建立因未捕获异常而断开的 websocket 连接：错误 [ERR_IPC_CHANNEL_CLOSED]：通道已关闭

我的环境详情：

  • 操作系统：Ubuntu 20.04
  • 节点版本：9.6.1
  • Qt 版本：5.9.1

我使用名为 javascript 的 APP 构建前端应用程序。 APP接收客户端的请求，并与负责创建worker的Browser Service（一个node js服务）建立websocket连接。Browser Service在过程中使用了一些原生的依赖（用c++编写）。架构如下：

我可以毫无问题地启动所有服务。当我尝试创建进程时，它失败并显示以下错误：

如果您能帮助我解决此问题，我将不胜感激。

更新

据我所知，Error [ERR_IPC_CHANNEL_CLOSED]: Channel closed 表示正在尝试向已关闭的进程发送消息。似乎工人死了，工人的消息exit:0 SIGSEGV
