Heroku app.json configuration not working for review app

Question

Below is my app.json:

{ "environments": { "review": { "addons": [ "heroku-postgresql:in-dyno" ], "scripts": { "postdeploy": "php artisan migrate --seed" } } } } 

In my understanding, a review app with such configuration should be starting with Postgres DB and run my script afterwards; the app starts, yet no Postgres is attached and I don't see any errors in Build log nor Application Logs.

How should my app.json be structured to do what I want?

Answer 1

in-dyno means a Postgres instance won't be attached - it'll be directly within the dyno itself. Not seeing errors in the build log would, thus, be normal.
