Answer 1

If your client id, client secret, and your javascript origins url is correct you might want to check whether the port you're using is exactly the same with the url you put in for javascript origins. I mistyped mine by one digit: e, g localhost:888 instead of localhost:8888 and got that error because my javascript origins was localhost:8888 not 888
