I cannot connect Postgres DB with Strapi on Heroku - postgresql

Question

I try to set up Strapi + PostgresDB on Heroku.
I follow this manual step by step https://strapi.io/documentation/3.0.0-beta.x/deployment/heroku.html
When I deploy to Heroku I get: Application error
heroku logs --tail shows

I see it asks about sqlite3 but I have it package.json
The project was inited with --quickstart but I have made ./config/environments/production/database.json

Answer 1

If you installed strapi with the --quickstart flag then by default it would provision a SQLite db for you.
since you loading a db config for postpres, make sure you installed pg.
you can npm/yarn remove sqlite3 from your package.json if you not using it locally, ie.you have postgres installed and the service is running.
delete your cache folder and then npm run build
now push to heroku and open.
fyi. it is recommended that you have database.js over database.json
eg.
module.exports = ({ env }) => ({
defaultConnection: 'default',
connections: {
default: {
connector: 'bookshelf',
settings: {
client: 'postgres',
host: env('DATABASE_HOST'),
port: env.int('DATABASE_PORT'),
database: env('DATABASE_NAME'),
username: env('DATABASE_USERNAME'),
password: env('DATABASE_PASSWORD'),
ssl: env.bool('DATABASE_SSL'),
},
options: {}
},
},
});
In Heroku make sure that the postgres addon is provisioned.
check your config vars in heroku for the app is correct.
also make sure ./config/database.js or ./config/database.json has also been corrected to use the correct database.
