Puppeteer Uncatchable Target Closed Error

I am having problems with using puppeteer.
Every 10 to 50 requests I get the following error:

TargetCloseError: Protocol error (Network.getCookies): Target closed
at CallbackRegistry.clear (/app/node_modules/puppeteer-core/lib/cjs/puppeteer/common/Connection.js:153:36)

And the biggest problem with it is the fact that it is not catchable and therefore causes my whole app to crash.

I use await before every puppeteer-action and here is all of my code that involves puppeteer:

let browser = null;
try {
    browser = await puppeteer.launch({
        headless: "new",
        args: [
            `--user-agent=${userAgent}`,
            '--no-sandbox'
        ]
    });
    browser.on('disconnected', () => browserDisconnected = true)
    const page = await browser.newPage();

    await useProxy(page, proxyUrl);
    await page.goto(url);
    await setTimeout(pageLoadTimeout);
    await page.waitForSelector("#Title");

    const renderedContent = await page.content();
    const $ = cheerio.load(renderedContent);

    const title = $("#Title").html();

    output = { title: title };
} catch (error) {
    console.log(error);
    output =  { error: true, error: error.message };
} finally {
    try {
        if(browser !== null) {
            await browser.close();
        }
    } catch(error) {
        console.log("ERROR CLOSING BROWSER:");
        console.log(error);
    }
    return output;
}   

I've stripped the code from any tasks that don't involve puppeteer.

I am absolutely clueless on how to handle this error and I've pretty much seen any SO, Github, ... issue on this topic.
It would already be helpful if I could catch the error so it doesn't cause my whole server to crash and have to restart.

Where am I running the server?
In a docker container with the following platform --platform=linux/amd64 node:18 in Google App Engine.

Any help would be very appreciated!

Thanks to a hint in the right direction by @Yaroslavm, I've now found the cause and solution for this particular problem.

The issue was with await useProxy(page, proxyUrl); from the puppeteer-page-proxy'package. The error occurred internally within the package.

Luckily there is another way to use a proxy with Puppeteer.

I've found the following solution (https://pixeljets.com/blog/how-to-set-proxy-in-puppeteer/):

const oldProxyUrl = `http://${proxy.username}:${proxy.password}@${proxy.address}:${proxy.port}`;
 const newProxyUrl = await proxyChain.anonymizeProxy(oldProxyUrl);

browser = await puppeteer.launch({
   headless: "true",
   args: [
     `--user-agent=${userAgent}`,
     '--no-sandbox',
     `--proxy-server=${newProxyUrl}`
   ]
});

const page = await browser.newPage();

Done!

The link I provided above mentions more options which I have yet to test.
I hope I could help!

Puppeteer usually acts same way, when file execution was finished, but there are still some actions that are not properly awaited (in Promise pending status).

Are this functions async?

> const $ = cheerio.load(renderedContent);
>
> const title = $("#Title").html();

If yes - try to await for them to be resolved.
