Class "StoreFactory" not found

I'm trying to run the sample1.php class available at php client github repo that is a simple GridDB client in php, currently running it on ubuntu 22.4.1, using the command:

php sample1.php 127.0.0.1 10001 myCluster admin admin -->Person: name=diego status=true count=2 lob=ABDCS

This raises the error:

HP Fatal error:  Uncaught Error: Class "StoreFactory" not found in /home/diego/Documents/php_client/sample/sample1.php:7Stack trace:#0 {main}  thrown in /home/diego/Documents/php_client/sample/sample1.php on line 7

the php file is the following:

<?php        if (file_exists('griddb_php_client.php')) {        // File php wrapper is generated with SWIG 4.0.2 and below        include_once('griddb_php_client.php');    }    $factory = StoreFactory::getInstance();    $blob = pack('C*', 65, 66, 67, 68, 69, 70, 71, 72, 73, 74);    $update = true;    try {        // Get GridStore object        $gridstore = $factory->getStore(["host" => $argv[1],"port" => (int)$argv[2],"clusterName" => $argv[3],"username" => $argv[4],"password" => $argv[5]]);        // Create a collection container        $conInfo = new ContainerInfo(["name" => "col01","columnInfoArray" => [["name", Type::STRING],                                                        ["status", Type::BOOL],                                                        ["count", Type::LONG],                                                        ["lob", Type::BLOB]],"type" => ContainerType::COLLECTION,"rowKey" => true]);        $gridstore->dropContainer("col01");        $col = $gridstore->putContainer($conInfo);        // Change auto commit mode to false        $col->setAutoCommit(false);        // Set an index on the Row-key Column        $col->createIndex("name");        // Set an index on the Column        $col->createIndex("count");        // Put row: RowKey is "name01"        $ret = $col->put(["name01", false, 1, $blob]);        // Remove row with RowKey "name01"        $col->remove("name01");        // Put row: RowKey is "name02"        $col->put(["name02", false, 1, $blob]);        $col-> commit();        $mArray = $col->get("name02");        // Create normal query        $query = $col->query("select * where name = 'name02'");        // Execute query        $rs = $query->fetch($update);        while ($rs->hasNext()) {            $data = $rs->next();            $data[2] = $data[2] + 1;            echo("Person: name=$data[0] status=".($data[1] ? "true" : "false")                    ." count=$data[2] lob=$data[3]\n");            // Update row            $rs->update($data);        }        // End transction        $col->commit();        echo("success!\n");    } catch (GSException $e) {        for ($i= 0; $i < $e->getErrorStackSize(); $i++) {            echo("\n[$i]\n");            echo($e->getErrorCode($i)."\n");            echo($e->getLocation($i)."\n");            echo($e->getErrorMessage($i)."\n");        }    }?>

I have already tried to export all the global vars:

1. Write the following desctiption in /etc/php.ini.    extension=<PHP client library file directory path>2. Set LD_LIBRARY_PATH.    export LD_LIBRARY_PATH=${LD_LIBRARY_PATH}:<C client library file directory path>

Also checked if the server is running:

sudo systemctl status gridstore

this pritns the following:
