heroku run 'bundle exec ridgepole -c config/database.yml -E production -f Schemafile --apply'

Running bundle exec ridgepole -c config/database.yml -E production -f Schemafile --apply on ⬢ notodoo... up, run.8458 (Free)
[ERROR] no implicit conversion of nil into String

ridgepoleというgemを利用してあります。
以下のコマンドは実行済みです。
heroku run rails db:migrate

heroku run rake ridgepole:apply

heroku run 'bundle exec ridgepole -c config/database.for.heroku.ridgepole.yml -E production -f db/Schemafile --apply'

ちなみにdeviseにはSNS認証を実装してあります。

追記
https://hamayuzin.hatenablog.com/entry/2017/05/26/082527のサイトの方法もだめでした。

Answer 1

もう一度作り直して
heroku run rails db:migrate
の代わりに
heroku run 'bundle exec ridgepole -c config/database.for.heroku.ridgepole.yml -E production -f db/Schemafile --apply'
をやれば出来ました

Answer 2

heroku run rails db:migrate　-E production
してみてください
