Drupal pod fails to restart after installing OpenEuropa theme – EuropaComponentLibraryLoader class not found

[czaloumis]

Name and Version

bitnami/drupal:19.0.9

What steps will reproduce the bug?

1. Deploy the Bitnami Drupal Helm chart version 19.0.9 on an EKS cluster using either default bundled MariaDB database, or an external Amazon RDS instance
2. Wait for the Drupal pod to start successfully.
3. Follow the official OpenEuropa Theme installation steps inside the Drupal container to install the OpenEuropa Theme(note: for the composer-artifact install the 1.0.0-alpha1 version and for the oe_theme the 4.4.0 version).
4. Trigger a pod restart

What is the expected behavior?

The Drupal pod to restart successfully.

What do you see instead?

The Drupal pod fails to start again, and throws the following error during the database update step:Error: Class"OpenEuropa\Twig\Loader\EuropaComponentLibraryLoader" not found in /bitnami/drupal/themes/contrib/oe_theme/modules/oe_theme_helper/src/Loader/ComponentLibraryLoader.php The pod does not recover unless the Drupal volume and database are deleted and re-initialized.

Additional information

To isolate the problem, I created a test deployment using the official Drupal Docker image from DockerHub, not the Bitnami image. I performed the exact same installation steps (including the OpenEuropa theme), and in that setup, the pod restarts without any issue.
