Call to a member function getId() on array

[danaki]

Error caused by code:

            $queryBuilder = $this
                ->postRepository
                ->createQueryBuilder('p')
                ->select('p as post')
            ;

            $query = $this
                ->sphinx
                ->createQuery()
                ->select('id')
                ->from(...$this->sphinxIndices)
                ->match(['post_title', 'post_text'], $searchQuery)
                ->orderBy('post_date', 'desc')
                ->useQueryBuilder($queryBuilder, 'p', 'id')
            ;

Possibly can be fixed if last 'id' parameter can be a custom getter callable.
