▶ System Information I have install Strapi 4 on localhost by --quickstart flag. I have deployed it on Heroku by following this guide https://docs.strapi.io/developer-docs/latest/setup-deployment-guides/deployment/hosting-guides/heroku.html But it seems Strapi runs by local database not ./config/env/…

Thank you for your time guys. Actually I was using AWS RDS for database and I forgot to create a database there. Everything was fine in config variable
