Cannot read property 'focus' of null

I'm getting this error when I try to use your program, I think there's something wrong with the element handle that pulls the chromium window into focus but I have no idea what that could be.

Error: TypeError: Cannot read property 'focus' of null
    at focusAndType (C:\Users\[Censored Name]\Google Drive\Projects\gpt2\automate-tweetdeck-master\index.js:18:23)
    at logIn (C:\Users\[Censored Name]\Google Drive\Projects\gpt2\automate-tweetdeck-master\index.js:31:9)

    at async C:\Users\[Censored Name]\Google Drive\Projects\gpt2\automate-tweetdeck-master\index.js:115:5

Because of this it just opens the window and then doesn't control anything.

Hi @lflad sorry it doesn't work. There's a good chance this project is out of date now (and it was always somewhat buggy) but I'll fire it up again and see if I get the same error as you.

I was trying to solve a problem that I'm not sure was all that solvable. I'll update the readme to reflect that

Have you had any luck with this?

Right so I had a look and I get the same problem as you. The issue appears to be that the username and password fields (when logging into Tweetdeck) have changed. They used to have the class names specified here but now those lines of code are returning null because the class names have changed for whatever reason. I think Twitter has redone the login page. The script tells Chromium to focus() on the fields in order to type but it can't focus on null.

I've screenshotted the username element in Chrome Dev Tools for clarity (the password element is below it)

This is a buggy program at the best of times and to be honest I don't have a lot of time to fix it at the moment. If you fancy having a go at it yourself and submitting a pull request I'd welcome that. Thanks
