问题
I have a puppeteer script I run to reboot my modem. It has worked for I guess about a year with no problem. 5 days ago it stopped working. I was looking into it and realized that I am getting errors I didn't used to get when running it and the script fails. The thing is I didn't change anything. As far as I can see, the HTML hasn't changed either yet it is failing. So I wonder if there is a bug in chromium or puppeteer or if it handles things differently somehow?
Here's a codepen with https://codepen.io/michaelbierman/pen/qQjdYR
- HTML page
- puppeteer script
