openwhisk-composer 在进行并行组合时无法连接到 redis 服务器

Question

这里有人试过 openwhisk-composer composer.parallel()?

我的 openwhisk 操作似乎无法连接到 redis-server ive 设置，

当我使用 composer.parallel() 调用操作时它抛出错误

    ],

const composer = require('openwhisk-composer');

// complexwf.js
module.exports = composer.retain(
    composer.action('step-a', { action: function (params) {
        console.log('log-step-a', params);
        return { value: 'from-step-a' } 
    } }),
    composer.action('step-b', { action: function (params) { 
        console.log('log-step-b', params);
        return { value: 'from-step-b' } 
    } }),
    composer.parallel(
        composer.action('step-c', { action: function (params) { 
            console.log('log-step-c', params);
            return { value: 'from-step-c' } 
        } }),
        composer.action('step-d', { action: function (params) { 
            console.log('log-step-d', params);
            return { value: 'from-step-d' } 
        } }),
    )
);

关于我的设置的一些信息，我的 redis 服务器在 docker 上运行已尝试通过 vscode 中的 redis 资源管理器连接到我的 redis 服务器并且正在运行，

能够让它工作，我将输入中的 redis uri 更改为容器 ip 而不是 public ip，所以输入是这样的

{
    "name": "complexwf",
    "params": {
        "$composer": {
            "openwhisk": {
                "ignore_certs": true
            },
            "redis": {
                "uri": "redis://172.17.0.2:6379"
            }
        },   
        "value": "from-input" 
    }
}
