Selenium C#: Test cannot be executed in the old Browser versions

[Vadivel Sekar]

Hi,

Issue: In Selenium C#, test script execution is failing in the old versions of browsers

Details:

Selenium WebDriver: V 4.1.0

Chrome                       : V 86.0.4240.75

Chrome Driver          : V 86.0.4240.22 (Release note says: Supports Chrome version 86)

Screenshots:

Error Message:

Message:
System.InvalidOperationException : session not created: This version of ChromeDriver only supports Chrome version 90
Current browser version is 86.0.4240.75 with binary path C:\Program Files\Google\Chrome\Application\chrome.exe (SessionNotCreated)
TearDown : System.NullReferenceException : Object reference not set to an instance of an object.

  Stack Trace:

That is to be expected.

You are using a newer version of ChromeDriver that does not support the older version of Chrome that you are running.
