Answer 1

The line below is causing you trouble

profile.key_expires = (timezone.now() + datetime.timedelta(days=2)),

You are setting key_expires as tuple instead of string. Change it to

profile.key_expires = timezone.now() + datetime.timedelta(days=2)

Also remove the comma from the end of the line mentioned above.
