Javascript 如何使用 puppeteer 抓取多个页面

我正在try 使用Puppeter从多个页面中获取价格.我遇到的问题是，编写一个包含所有刮取数据的JSON文件.问题是，如果我试图用async function中的变量编写文件，我会得到一个错误，说明该变量尚未声明.

async function scrapeVMZ(url) {
    const browser = await puppeteer.launch();
    const page = await browser.newPage();
    await page.goto(url);

    const [vmzel1] = await page.$x('//*[@id="__layout"]/div/div[1]/section/div/div/div[2]/div[2]/div[1]/div/div/div[2]/div/div[1]/span[2]');
    const vmztxt1 = await vmzel1.getProperty('textContent');
    const vmzRawTxt1 = await vmztxt1.jsonValue();


    const [vmzel2] = await page.$x('//*[@id="__layout"]/div/div[1]/section/div/div/div[2]/div[2]/div[1]/div/div/div[2]/div/div[1]/span[4]/b');
    const vmztxt2 = await vmzel2.getProperty('textContent');
    const vmzRawTxt2 = await vmztxt2.jsonValue();

    console.log({vmzRawTxt1, vmzRawTxt2});
    const vmz01 = JSON.stringify(vmzRawTxt1);
    const vmz02 = JSON.stringify(vmzRawTxt2);
    console.log(vmz01, vmz02);
    browser.close();
}
scrapeVMZ('https://www.vmzviagens.com.br/ingressos/orlando/walt-disney-orlando');


async function scrapeMB(url) {
    const browser = await puppeteer.launch();
    const page = await browser.newPage();
    await page.goto(url);

    
    const [mbel1] = await page.$x('/html/body/section[3]/div/div/div[2]/div[1]/div/div[2]/a[1]/span[2]/span/div/div[2]/span');
    const mbtxt1 = await mbel1.getProperty('textContent');
    const mbRawTxt1 = await mbtxt1.jsonValue();


    
    const [mbel2] = await page.$x('/html/body/section[3]/div/div/div[2]/div[1]/div/div[2]/a[1]/span[2]/span/div/div[4]/span');
    const mbtxt2 = await mbel2.getProperty('textContent');
    const mbRawTxt2 = await mbtxt2.jsonValue();

    console.log({mbRawTxt1, mbRawTxt2});
    const mb01 = JSON.stringify(mbRawTxt1);
    const mb02 = JSON.stringify(mbRawTxt2);
    console.log(mb01, mb02);
   
    browser.close();
}
scrapeMB('https://www.ingressosmagicblue.com.br/produtos/?mpage=2');

如何使用上面的代码编写一个文件，将变量vmz01, vmz02和mb01, mb02存储在JSON文件中，如下面的示例所示？

let abc = {        
        "MB": {
            preco: mb01,
            preco2: mb02
        },
        "VMZ": {
            preco: vmz01,
            preco2: vmz02
        }
    };
