[BUG] <Getting webdriver exception "unknown error: unable to discover open pages" when running the test on server through ADO test plan. Code works locally> #1411
Please help! This is happening for any test we're running through ADO test plan. We get Webdriver exception below when running on a Server VM using Edge Driver. The script works fine when running locally but fails repeatedly on server.
Error message:
