承诺和异步等待不起作用-未经处理的拒绝位于：承诺承诺{<；拒绝>；'；节点数据'；}原因：未定义-node.js
我被困在过去的几天里，我使用openshift模块使用node.js获取所有pod及其状态承诺和异步等待不起作用-未经处理的拒绝位于：承诺承诺{<；拒绝>；'；节点数据'；}原因：未定义-node.js,node.js,promise,async-await,try-catch,Node.js,Promise,Async Await,Try Catch,我被困在过去的几天里，我使用openshift模块使用node.js获取所有pod及其状态 npm i okd-api 下面是获取pod列表的代码段 aws_app.get('/fetchList', async function(req,res){ await getServices().then((allServices)=>{

有人能告诉我哪里出了问题吗检查这是否运行，如果看到编译错误，请更正几位

你的控制台日志打印是什么？你在哪里需要帮助？不要混用
。然后（…）。用async/await捕获（…）awaitawaitawaitokd.namespace（）.pod.watch_all（）pods.map（）async/await等待pods.map（（v）=>wait
