Error: [rebrowser-patches] acquireContextId failed

Sometimes, page.evaluate(...) throws the following error:

Error: [rebrowser-patches] acquireContextId failed

This happens quite often but I can't figure out what triggers it. This may be due to the fast loading of a page.

workaround, didn't test it thoroughly yet

async function evaluateInPage(page, content) {
  while (true) {
    let retry;
    let r= await page
      .evaluate(content)
      .catch(
        (e) => (retry = e?.toString().includes("acquireContextId failed"))
      );

    if (retry) {
      await new Promise((R) => setTimeout(R, 300));
    } else {
      return r;
    }
  }
}

Do you have any specific website where it happens the most? Could it be something because of many iframes on the page? Also, try to set process.env.REBROWSER_PATCHES_DEBUG=1, it will give you some debug messages right before this error happens.

Btw, I just added another place for logging this error, please use the latest patch and process.env.REBROWSER_PATCHES_DEBUG=1.

Thank you for providing the patches! However, I haven't been able to use them successfully so far. For instance, I encounter the error 'acquireContextId failed' already with this code snippet. This is just an example to show that fetch does not work inside evaluate.

const browser = await puppeteer.launch({
  headless: false,
  executablePath: config.googleChromePath,
});
const context = await browser.createBrowserContext();
const page = await context.newPage();
const url = "https://httpbin.org/ip";
await page.goto(url);
const ip = await page.evaluate(async (url) => {
  const response = await fetch(url);
  const data = await response.json();
  return data.origin;
}, url);
console.log("IP:", ip);

Moreover, I get the following issue occasionally:

I couldn't find a solution yet, even retrying the evaluation many times. It seems like the library is causing puppeteer to lose access to contexts's ids in some situations.

📣 I just released a new version of rebrowser-patches with a completely new fix for Runtime.Enable leak. This fix doesn't lose access to main context and also works in workers 🎉 It's a complete drop-in replacement, so you don't need to change any of your existing code. Please try your code with new version.
