Fixing Drupal configuration dependency issues using Drush commands

In this blog post, we'll discuss how to resolve configuration dependency issues in Drupal using Drush commands. This is a common problem faced by developers while importing configurations, and we'll provide you with an SEO-optimized solution to tackle this issue effectively.

Understanding Configuration Dependency Issues

Configuration dependency issues occur when a Drupal configuration file depends on another configuration that doesn't exist or will not exist after import. These issues can be problematic and can lead to errors during the import process. In this tutorial, we'll focus on a specific example:

Configuration core.entity_view_display.node.article.custom_article_teaser_storm depends on the field.field.node.article.comment configuration that will not exist after import. in Drupal\Core\Config\ConfigImporter->validate() (line 759 of /var/www/html/web/core/lib/Drupal/Core/Config/ConfigImporter.php).

Using Drush PHP-Eval to Remove Configuration Dependencies

Drush is a powerful command-line tool for Drupal that provides various commands to manage your Drupal installation. One such command is `drush php-eval`, which allows you to execute PHP code within the Drupal environment. We can use this command to resolve configuration dependency issues directly:

drush php-eval '$config = \Drupal::configFactory()->getEditable("core.entity_view_display.node.article.custom_article_teaser_storm"); $dependencies = $config->get("dependencies.config"); if (($key = array_search("field.field.node.article.comment", $dependencies)) !== false) { unset($dependencies[$key]); $config->set("dependencies.config", array_values($dependencies))->save(); }'

This command performs the following steps:

1. Retrieves the editable configuration object for `core.entity_view_display.node.article.custom_article_teaser_storm`.
2. Gets the current `dependencies.config` array from the configuration.
3. Searches for the problematic dependency `field.field.node.article.comment` in the array and removes it if found.
4. Sets the updated `dependencies.config` array and saves the configuration.

After running this command, you can verify the changes by running:

drush cget core.entity_view_display.node.article.custom_article_teaser_storm dependencies

Finally, import the updated configuration:

drush config:import

Now, the dependency should no longer cause any issues during the import process.
