Better Version of the fix:

  /**
   * @var array
   */
  protected array $settings = [];

  /**
   * Check if javascript validation is activated
   *
   * @return bool
   */
  public function isServerValidationEnabled(): bool {
    return !empty($this->settings['validation']['server']) && $this->settings['validation']['server'] === '1';
