This warning can popup in some cases when setting formatter display:
Warning: Undefined array key "formatter_settings" in Drupal\custom_field\Plugin\Field\FieldFormatter\BaseFormatter->calculateDependencies()
Which then leads to fatal type error:
TypeError: Drupal\custom_field\Plugin\CustomFieldFormatterBase::calculateFormatterDependencies(): Argument #1 ($settings) must be of type array, null given, called in /var/www/html/docroot/modules/contrib/custom_field/src/Plugin/Field/FieldFormatter/BaseFormatter.php on line 409 in Drupal\custom_field\Plugin\CustomFieldFormatterBase->calculateFormatterDependencies() (line 75 of /var/www/html/docroot/modules/contrib/custom_field/src/Plugin/CustomFieldFormatterBase.php).
I triggered this by setting one of the formatter fields (boolean type) to hidden. The field did not yet have any formatter_settings saved in config.
Modify calculate dependencies to check existence of formatter settings.
/**
* {@inheritdoc}
*/
public function calculateDependencies() {
$fields = $this->getSetting('fields');
$dependencies = parent::calculateDependencies();
if (!empty($fields)) {
foreach ($fields as $name => $field) {
$plugin = $this->customFieldFormatterManager->createInstance($field['format_type']);
if (method_exists($plugin, 'calculateFormatterDependencies')) {
if (isset($field['formatter_settings'])) {
$plugin_dependencies = $plugin->calculateFormatterDependencies($field['formatter_settings']);
$dependencies = array_merge_recursive($dependencies, $plugin_dependencies);
}
}
}
}
return $dependencies;
}Create patch.
