The reason you're getting the error is that you're calling a value from a list which is empty. To call the first item in the list you say list[0]. In this case the list you're calling is empty so the first value doesn't exist hence the error.
I've ran your code and there is no #id value of 'recaptcha-token' which is why the code is returning an empty list. The only place a recaptcha token is needed is for signing up so I would suggest trying to log in without creating the authenticity_token.
