Error actionCreate

I can not run actionCreate function. I am writing custom controller for entity, but am getting error.I can not add records to the database. --> "bad server response"

<?php

namespace Espo\Custom\Controllers;

class BesProduct extends \Espo\Core\Templates\Controllers\Base
{
    protected function getEntityManager()
    {
        return $this->getContainer()->get('entityManager');
    }
    
    public function actionCreate($params, $data, $request)
    {
        //return json_encode($data);
        
        $pdo = $this->getEntityManager()->getPDO();
        
        if($data->status == "3"){
            /* Get user */
            $userSql = "SELECT career_steps_id FROM user WHERE id='".$data->assignedUserId."'";
            $userResult = $pdo->prepare($userSql);
            $userResult->execute();
            $userRow = $userResult->fetch(\PDO::FETCH_ASSOC);
            
            /* Get career step */
            $stepCommissionSql = "SELECT * FROM career_commissions WHERE career_steps_id='".$userRow['career_steps_id']."'";
            $stepCommissionResult = $pdo->prepare($stepCommissionSql);
            $stepCommissionResult->execute();
            $stepCommissionRow = $stepCommissionResult->fetchAll(\PDO::FETCH_ASSOC);
            
            $x = 1;
            while($x <= $stepCommissionRow['payment_period']){
                $commissionValue = $data->amount * $stepCommissionRow['commission_value'] / 100;
                $totalPay = $commissionValue / $stepCommissionRow['payment_period'];
                
                /* Update career history table */
                $id = uniqid();
                $commissionSql = "INSERT INTO career_history (id,name,deleted,description,created_at,modified_at,created_by_id,modified_by_id,assigned_user_id,payable,month) 
                                                   VALUES ('".$id."','','0','','".$date."','".$date."','1','1','".$data->assignedUserId."','".$totalPay."','".$x."')";
                $sthCommission = $pdo->prepare($commissionSql);
                $sthCommission->execute();
                $x++;
            }
        }
    }
}
