Can verify this as of about 5 minutes ago. Simply did the following to be precise:
this actually was able to pull up my browser as intended, original heroku keys:add would try to when it was failing and fail to pull up the browser as well for some reason.
then I would login to heroku using respective login information and wait for it to confirm I was logged in.
and this would be successful this time around
hope this helps
ANOTHER NOTE: It’s important to note here that it seems to be that you need to be in the my_first_apps or whatever you named and made the original directory in. I believe the problem some people might be having is that they might be putting this lesson down in the middle of it and booting their VM up the next day to start without realizing that everything from the heroku section needs to be in the directories specified previously and also after “git init” has been executed.
Someone who is much more experienced than me please feel free to come along and add to this / correct me as I’ve only made it this far in the course and am pretty ignorant to the specifics.
