How to reload page in Puppeteer?

Question

I would like to reload the page whenever the page doesn't load properly or encounters a problem. I tried page.reload() but it doesn't work.

for(const sect of sections ){

            // Now collect all the URLs
            const appUrls = await page.$$eval('div.main > ul.app-list > li > div.app-info a.app-info-icon', links => links.map(link => link.href));

            // Visit each URL one by one and collect the data
            for (let appUrl of appUrls) {
                var count = i++;
                try{
                    await page.goto(appUrl);
                    const appName = await page.$eval('div.det-name-int', div => div.innerText.trim());
                    console.log('\n' + count);
                    console.log(appName);
                } catch(e){
                    console.log('\n' + count);
                    console.log('ERROR', e);
                    await page.reload();
                }

            }

        }

It gives me this error:

Some links are unable to load successfully. When I refresh those pages manually, it works. So I hope there is a function or a method that can help me reload my page automatically when there is an error.

This works for me:

await page.reload({ waitUntil: ["networkidle0", "domcontentloaded"] });
