Could not start a new session. Response code 500. Message: unknown error: DevToolsActivePort file doesn't exist | Selenium, TestNG, Cucumber, Chrome browser

While we were trying to run the automation code in AWS workspaces, we stuck with the following error message and the temporary solution was to add the following argument to the chrome browser. 

options.addArguments("--remote-debugging-port=9222"); 

The observation is that even after adding this argument, we have to make sure that the browser is NOT opened in the AWS instance. 

[RemoteTestNG] detected TestNG version 7.4.0
