The NullPointerException is thrown because Solr is trying to get the unique key from the list of fields returned by the query.

The default uniqueKey field is id. Adding it to the field list fixes the error.

// Add the documents ids to be elevated to the search query.
if (isset($query_item_ids['elevate']) && is_array($query_item_ids['elevate'])) {
  $query->setOption('solr_param_elevateIds', implode(',', $query_item_ids['elevate']));
  $query->setOption('solr_param_fl', 'id,[elevated]');
}
