getting selenium error - disconnected: received Inspector.detached event using chrome driver version 2.20.x

Question

When my script is trying to sendkeys for username after opening login page, I am getting disconnected: received Inspector.detached event error.

Console details:

Answer 1

Without having the actual test code, my best guess is that com.demoProject.loginAllTime(), which is calling sendKeys(), must be sending either Ctrl-Shift-I, or Ctrl-Shift-J, or Ctrl-Shift-C, each of which will open the Chrome DevTools on Windows.

As mentioned in the comments, if DevTools is opened during a WebDriver run, ChromeDriver will be automatically disconnected, producing the error:

received Inspector.detached event

It doesn't seem to be possible to get that error any other way.
