部署Camunda Modulator的JS Worker时Node编译报错求助

运行nodejs ./CheckRequestFeasibilityWorker.js时出现以下错误：

(node:27539) Warning: To load an ES module, set "type": "module" in the package.json or use the .mjs extension.
(Use `nodejs --trace-warnings ...` to show where the warning was created)
/JsWorkers/CheckRequestFeasibilityWorker/CheckRequestFeasibilityWorker.js:1
import { Client, logger } from "camunda-external-task-client-js";
^^^^^^

Node.js v18.15.0

一、解决ES模块语法错误 #

错误提示已明确给出两种解决方式，任选其一即可：

方式1：修改package.json #

在项目根目录的package.json中添加"type": "module"字段：

{
  "type": "module",
  "dependencies": {
    "camunda-external-task-client-js": "^..."
  }
}

方式2：重命名文件扩展名 #

将CheckRequestFeasibilityWorker.js改为CheckRequestFeasibilityWorker.mjs，然后运行：

nodejs ./CheckRequestFeasibilityWorker.mjs

二、修复代码中的其他问题 #

代码还有两处错误，不修复会导致运行失败：

1. Math对象拼写错误：JavaScript中随机数方法是Math.random()，需首字母大写
2. Variables未导入：Variables需要从camunda-external-task-client-js包中引入

修正后的完整代码：

import { Client, logger, Variables } from "camunda-external-task-client-js";

// 客户端配置
//  - 'baseUrl': 流程引擎地址
//  - 'logger': 自动记录关键事件的工具
const config = { baseUrl: "http://localhost:8080/engine-rest", use: logger };

// 创建自定义配置的客户端实例
const client = new Client(config);

// 订阅主题：'check-request-feasibility'
client.subscribe("check-request-feasibility", async function({ task, taskService }) {
  // 业务逻辑：随机生成可行性结果
  const Is_feasible = Math.random() >= 0.5;
  const processVariables = new Variables();
  processVariables.set("Is_feasible", Is_feasible);
  // 完成任务
  await taskService.complete(task);
});
