TypeError on array_filter()

Hi @lucian_pana,

I tried to reproduce it, but not able to.

I am not sure why are you getting this error because in the following form field, the default value is array. SO the null given in array_filter() is not possible.

    $form['local_task_enabled_entity_types']['entity_types'] = [
      '#type' => 'checkboxes',
      '#title' => $this->t('Local task entity types'),
      '#options' => $tabs_options,
      '#default_value' => $config->get('local_task_enabled_entity_types') ?: [],
    ];

Please check again.

Thanks
Samit K.

Same problem here

* edit: removing module paragraphs_library seemed to fix this. *

Entity Usage 8.x-2.0-beta12
Drupal core 10.2.2

TypeError: array_filter(): Argument #1 ($array) must be of type array, null given in array_filter() (line 273 of modules/contrib/entity_usage/src/Form/EntityUsageSettingsForm.php).

Saving form causes this error out of the box.

config value local_task_enabled_entity_types is not returned by $this->config('entity_usage.settings') , breaking this code
array_filter($config->get('local_task_enabled_entity_types')) !== array_filter($form_state->getValue('local_task_enabled_entity_types')['entity_types']);

Hi
I try to reproduce the issue in Drupal 10.2 with Entity Usage 8.x-2.0-beta12 i am not getting any error. Configurations saved successfully.

if you still facing issue try this changes in the form.

$local_task_enabled_entity_types = $config->get('local_task_enabled_entity_types');
$local_tasks_updated = array_filter($local_task_enabled_entity_types ?? []) !== array_filter($form_state->getValue('local_task_enabled_entity_types')['entity_types']);

I am experiencing the same error. The provided snippet fixes it for me.

The issue is with this code on line 273:

array_filter($config->get('local_task_enabled_entity_types'))

When you first install the module and go to configure it, $config->get('local_task_enabled_entity_types') will be NULL. So adding a simple ?? [] to ensure array_filter() has an empty array in this case would make sense.

#10 fixed the error for me.

#9 is not correct - when you first install the module $config->get('local_task_enabled_entity_types') will return an empty array.

$ vendor/bin/drush en entity_usage -y
 [success] Module entity_usage has been installed. (Permissions - Configure)

$ vendor/bin/drush ev "var_dump(\Drupal::configFactory()->getEditable('entity_usage.settings')->get('local_task_enabled_entity_types'));"
array(0) {
}

The reason this issue exists is because #2932559: Make it easier to access entity usage list of an entity did not have an upgrade path. We could add one here. It'd be something like

/**
 * Initialize the "local_task_enabled_entity_types" config value to an empty array.
 */
function entity_usage_update_8207(&$sandbox) {
  $config = \Drupal::configFactory()->getEditable('entity_usage.settings');
  $entity_types = $config->get('local_task_enabled_entity_types');
  if ($entity_types === NULL) {
    $config->set('local_task_enabled_entity_types', [])->save(TRUE);
  }
}

Used a post update so we got config sorting for free.

This fixes the problem by providing the missing update path.

Merging...
