Pull Bins for Location

[rotarustefan]

Hi, I need to Pull all the bins for each locations, but I get an empty response:

$location = new RecordRef;
        $location->internalId = (string) $locationId;
        $location->type = RecordType::location;

        $searchField = new SearchMultiSelectField;
        $searchField->searchValue = [$location];
        $searchField->operator = SearchMultiSelectFieldOperator::anyOf;

        $search = new BinSearchBasic;
        $search->location = $searchField;

        $request = new SearchRequest;
        $request->searchRecord = $search;
        logger()->debug(json_encode($request));
        $response = $this->client->search($request);
        logger()->debug(json_encode($response));

     In netsuite there are bins for the location I'm trying to pull the bins, but I get: 
    
    {"searchResult":{"status":{"statusDetail":null,"isSuccess":true},"totalRecords":0,"pageSize":null,"totalPages":0,"pageIndex":null,"searchId":"WEBSERVICES_8238247_SB1_090320241197563719718480722_d5fe4358","recordList":{"record":null},"searchRowList":null}}
