The expression empty($items) ? null : current($items); of type Behat\Mink\Element\NodeElement|false adds false to the return on line 145 which is incompatible with the return type documented by Drupal\TqExtension\Utils\XPath\InaccurateText::find of type Behat\Mink\Element\NodeElement. It seems like you forgot to handle an error condition.
