从气流运行node.js命令时，我无法执行任何异步操作。我正在使用bash运算符来触发节点脚本。脚本中的所有同步操作都可以正常工作，但是一旦执行了一些异步操作，它就会异常退出。
我正在使用Apache Airflow 1.10.3执行数据管道。我需要触发具有异步I / O的node.js文件。 BashOperator可以很好地运行所有先前的作业。一旦我触发了节点代码，它将执行代码中的任何同步部分，但是当出现一些异步函数时，代码将终止。我尝试了一个简单的代码，在控制台上打印了一些值，然后进行了设置超时并在超时内进行了控制台。如果我在普通的CLI上运行此代码，它将运行良好，但是当在气流中使用BashOperator运行相同的代码时，它将在打印第一个同步控制台后终止。我尝试从shell脚本，scala编译代码，python代码和C代码调用node.js文件，并在气流上运行时遇到相同的错误。
console.log("This console is working");
setTimeout(function(){console.log("This console is working after
timeout");},5000);
以下是我在运行上述代码时收到的错误消息
