Driver info: driver.version: unknown
I tried below solution and didn't work for me.
Solution 1
This couldn't do due to my machine restriction
Other question I have is even after replacing the correct chromedriver in the below location when I start the server it still shows the wrong one. (i.e. chromedriver_75.0.3770.8.exe, But I replace that with chromedriver_74.0.3729.6.exe which is my current browser version.
File Location: protractor-cucumber-typescript\node_modules\protractor\node_modules\webdriver-manager\selenium
logs when start the server
λ npm run webdriver-start

So as a resolution Can I pointing to the chromedriver specifically? What is the relationship between selenium-server-standalone-3.141.59.jar and the chromedriver? Is there a way to find the compatible chromedriver version for this jar
In my case I don't have access to update or downgrade my machine chrome browser version. So how it's possible to change the web driver version to align with chrome browser version.

Answer 1

I figured out the issue here and managed to have resolution.
Problem : Even though I placed the matching chromedriver.exe in path (c:\Repository\GitExt\Protractor\protractor-cucumber-typescript\node_modules\protractor\node_modules\webdriver-manager\selenium) it's still looking for the original version which is coming fromwebdriver-update command.
So what I did was
Removed chromedriver from the above path.
Add the preferred one in some folder location and set that in env. variables. So if the driver is missing in the project folder it always goes to set path in the env. variables which the right one.
Despite of above solution I just wondering how I can change the driver version when run webdriver-update command?
