Error in QueryController, missing metastoreApiResponse

[thierrydallacroce]

The Datastore's QueryController extends AbstractQueryController, and uses its $metastoreApiResponse on line 45 in:

return $this->metastoreApiResponse->cachedJsonResponse(

However, AbstractQueryController declares that property as private, rendering it unreachable by its children, resulting in the following PHP error:

Error: Call to a member function cachedJsonResponse() on null in Drupal\datastore\Controller\QueryController->formatResponse()
(line 45 of .../docroot/modules/contrib/dkan/modules/datastore/src/Controller/QueryController.php)
