How to solve cookie sqlite error 1555? (Python & Selenium)
Unfortunately I'm having the same issue with chromedriver 2.35 on chrome 65. It just appeared in the last week, though perhaps an upgrade to chromedriver 2.37 will fix this.
The odd part is, I'm only opening one driver in this case (and disposing it correctly), and it still occurs. So I expect this is a bug in chromedriver that's popping up. Which versions of chromedriver/chrome are you running?
