Code is using a deprecated function
Use a smart date field in Drupal 10.2.0 and above
User deprecated function: Passing a string to Drupal\options\Plugin\Field\FieldType\ListItemBase::extractAllowedValues() is deprecated in drupal:10.2.0 and will cause an error from drupal:11.0.0. Use an array instead. See https://www.drupal.org/node/3376368 → in Drupal\options\Plugin\Field\FieldType\ListItemBase::extractAllowedValues() (line 406 of core/modules/options/src/Plugin/Field/FieldType/ListItemBase.php).
Update code / config so that values are stored as an array
From SmartDateWidgetBase:
$increments = SmartDateListItemBase::parseValues($defaults['default_duration_increments']);
From SmartDateListItemBase:
public static function parseValues($values) {
// Use the ListItemBase parsing function, but don't allow generated keys.
$result = static::extractAllowedValues($values, 1);
return $result;
}
