Question

我使用puppeteer-cluster + node js。我有一些剧本。我是新手

该脚本运行到一半，然后结束，不再执行。我一直在寻找解决方案已有一个星期，我不知道这是怎么回事。帮帮我，请在这里输入代码

const { Cluster } = require('puppeteer-cluster-delay');

(async () => {
    const cluster = await Cluster.launch({
        concurrency: Cluster.CONCURRENCY_CONTEXT,
        maxConcurrency: 2,
        puppeteerOptions: {headless: false,
        },
    });

    await cluster.task(async ({ page, data: url }) => {
        await page.goto('http://www.google.com/');
        await new Promise(resolve => {
            setTimeout(() => { // user is waiting for an asynchronous event
                try {
                    resolve();
                } catch (err) {
                    // handle error
                }
            }, 5000);
        });
        await console.log('1');
        await page.goto('http://www.google.com/');
        await new Promise(resolve => {
            setTimeout(() => { // user is waiting for an asynchronous event
                try {
                    resolve();
                } catch (err) {
                    // handle error
                }
