Puppeteer Issue #13

Open gewondjan opened 5 years ago

gewondjan commented 5 years ago

I got this issue when running the course on this trello card: https://trello.com/c/aMptNZuX

Execution stops and the command is not returned to powershell.

After running the course again, the error did not come up, but the error continues to appear intermittently with future courses. I have had it a total of 3 times as of this writing.
