I was using llama_index.readers.web.WholeSiteReader inside a docker container, which first gave a ValueError saying No chrome executable found in PATH. After I installed and setup the google-chrome and chromedriver, it gives SessionNotCreatedException.

Here's how I got the error -

>>> from llama_index.readers.web import WholeSiteReader
>>> test = WholeSiteReader(prefix="https://suryaanshrai.blogspot.com/")
Traceback (most recent call last):

  • I am getting the same. I see the browser window opening, the url is not changed by the driver. I am not running in Docker but in an Amazon WorkSpace. Commented Sep 17, 2024 at 10:25
  • For me, this error was there because i was using chrome in a container. Running chrome in headless mode worked for me. Although idk if the same would work for you Commented Jan 13 at 3:22
