I have set up digitalocean database and added the app as trusted source but the database connection fails over the composer installation process. Below are the errors.

and my app spec

- cluster_name: staging-db1
  db_name: racer
  db_user: doadmin
  engine: MYSQL
  name: staging-db1
  production: true
  size: professional-xs
  version: "8"
  - component:
      name: testapp
        prefix: /
name: racer
region: sgp
- build_command: npm run build
  environment_slug: php
    scope: RUN_TIME
    value: ${staging-db1.DATABASE_URL}
    branch: staging
    deploy_on_push: true
    repo: wfftt/testapp
  http_port: 8080
  instance_count: 2
  instance_size_slug: professional-xs
  name: racer
  run_command: heroku-php-apache2 public/ && composer install --ignore-platform-reqs
    && php artisan migrate:fresh
  source_dir: /

I tested the database and the app running on my local were able to connect by adding my ip to the trusted source. Any idea?

Hi there,

Indeed, during the build stage the App Platform does not have access to the Managed databases.

In your case, you most likely have a post run script defined somewhere in your composer.json file which is causing the problem. What you could do is to track down the specific command defined in the composer.json file that is causing the problem and remove it from there.

Here is an example of a composer.json file that I have for an open-source project that I maintain which works with the App Platform:

Feel free to share your complete composer.json file here so I could take a look as well and try to spot which script might be causing the problem.
