Zombie headless browser in Node.js does not load URL; error: undefined promise method. Tested on Linux and Darwin. Example:
const simEngine = require('zSim'); simEngine.get('http://demo.com');
I encountered a similar issue when switching between Node.js versions. The error about an undefined promise method sometimes indicates that the version of the headless browser or its dependencies is not fully compatible with the current Node.js API. I resolved the error by ensuring that I was using the latest compatible release and by switching to the more standard open method. It is also worth checking if the promise chain is properly implemented for URL navigation. In my case, updating the package and reviewing related issues in the repository helped resolve the navigation error.
