Using Puppeteer for WebSocket operations yields an undefined symbol error when closing the browser. Example:
const autoLib = require('puppeteer');
(async () => {
const instance = await autoLib.launch();
await instance.terminate();
})();
hey, i had a simlar issue. using terminate() isnt valid. instead, call instance.close() to shut the broweser down properly. hope this helps ya
hey there, seems the internatl mistake is calling terminate() which puppeteer never had. try using browser.close() and double-check your version. that helped me tons!
In my experience, the error stems from using a method that Puppeteer does not support. The terminate() method isn’t part of the Puppeteer API, which is why it results in an undefined symbol error when trying to close the browser. Instead, the proper way to shut down the browser is to use the close() method. For example, after launching the browser, invoke await instance.close() to gracefully end the session. Updating your code to reflect this change resolved similar issues in my projects and aligns better with Puppeteer’s design.
Encountering a similar error was frustrating until I discovered that using terminate() was the root of the issue. In my setup, using the close() method instead not only complied with the Puppeteer API but also resulted in smoother shutdowns of the browser instance. I initially overlooked that the Puppeteer team had designed the module with browser.close() in mind. Ensuring that my code strictly adheres to the documented API prevented any unexpected behavior, and I highly recommend double-checking method names against the official docs.
The issue you’re encountering appears to be due to invoking a method that isn’t part of Puppeteer’s officially supported API. In my projects, I once encountered a similar problem where calling terminate() resulted in an error because it simply wasn’t a recognized function. I resolved the issue by switching to the browser.close() method. It is essential to follow the documented API to avoid unexpected behavior. Additionally, ensuring that the Puppeteer instance is properly managed throughout the lifecycle of your script helped in preventing similar issues.
