Nested query in querybuilder not working

[karthikeyan r]

I am creating a querybuilder to find records containing first names like jon, leo inside a nested group, but i endup getting an exception.

{"query":{"bool":{"must":[{"nested":{"path":"author","query":{"bool":{"must":[{"terms":{"author.firstName":["jon","leo"]}}]}}}}]}}}

Here is the exception

Fatal error: Uncaught exception 'Elastica\Exception\ResponseException' with message 'failed to create query: {

  "bool" : {

    "must" : [

      {

        "nested" : {

          "query" : {

            "bool" : {

              "must" : [

                {

                  "terms" : {

                    "author.firstNa in C:\Workspace\kcp\vendor\ruflin\elastica\lib\Elastica\Transport\Http.php on line 172

Here is my querybuilder query that i wrote

$firstNames = ['Jon', 'Leo']

$queryBuilder = new QueryBuilder(new Version240());

$queryBuilder->query()

        ->bool()
            ->addMust($queryBuilder->query()->nested()
                ->setPath('author')
                ->setQuery(
                    $queryBuilder->query()->bool()
                        ->addMust($queryBuilder->query()->terms(
                            'author.firstName',
                            $firstNames
                        ))
                )
            );

Even the regular query doesnt seems to work

$query = new Query();
$search = new Search($elasticSearchClient);

$authorTerms= new Terms();
$authorTerms->setTerms('author.firstName', ['jon', 'leo']);
$authorTermsBoolQuery = new BoolQuery();
$authorTermsBoolQuery ->addMust($cityState);


$nestedQuery = new \Elastica\Query\Nested();
$nestedQuery->setPath("author");
$nestedQuery->setQuery($authorTermsBoolQuery );

$boolQuery = new BoolQuery();
$boolQuery->addMust($nestedQuery);
$query->setQuery($boolQuery);

$search->setQuery($query);

//echo $numberOfEntries = $search->count();
print_r(json_encode($query->toArray()));

Am i missing something? 
Appreciate your help and support

Thanks,

Which version of elasticsearch are you using?
