Fix broken media previews | erdfisch.de 🐠

media-install.sh

drush php-eval "\Drupal::moduleHandler()->loadInclude('media', 'install');media_install();";

Issue:

The error log is full of the warning "Warning: copy(public://media-icons/generic/generic.png)" and the media library shows no previews. This can happen when environments are set up based on a database dump and without properly transferring the files. The media icons are usually created during the installation of the media module, which will never happen in this scenario.

Solution:

Trigger the install hook of the Core Media module. It will take care of creating those files. Use the provided snippet.
