Selenium missing or invalid 'entry.level' Error

Question

I'm trying to run a selenium test which should work just fine (hasn't changed and used to work) but I'm getting this strange error.

System.InvalidOperationException : unknown error: cannot determine loading status

from unknown error: missing or invalid 'entry.level'

  (Session info: chrome=63.0.3239.84)

  (Driver info: chromedriver=2.25.426923 (0390b88869384d6eb0d5d09729679f934aab9eed),platform=Windows NT 10.0.15063 x86_64)

...

What is this "missing or invalid 'entry.level'" error and how do I fix it?

Answer 1

I resolved this error by updating my chrome driver to the latest version. Download the latest and replace the older version with the latest version.

Here is the link to the latest version:
