I'm trying to follow the instructions on migrating to Cedar (except I did a major rewrite so this isn't a branch of the previous app but a separate one) and stuck at the db migration step. I installed the pgbackup and heroku postgresql addons but get this result:
j3(master) : heroku pgbackups:restore DATABASE heroku pgbackups:url --app dada-foe-110
--app something-something-4311
32mQkEpWyJdfplOnXhlCnCRsoxYE12-05-25 --app something-something-4311
EXTERNAL_BACKUP <---restore--- b002.dump
! WARNING: Destructive Action ! This command will affect the app: something-something-4311 ! To proceed, type "something-something-4311" or re-run this command with --confirm something-something-4311

! An error occurred and your restore did not finish.
! The backup url is invalid. Use pgbackups:url
to generate a new temporary URL.
