I'm working on a request to pick up some result from the database but I have an error and I don't know how to resove it

in my repository :

public function findBySearchField($salary, $contract, $experience, $training)

 return $this->createQueryBuilder('a')
 ->andWhere('a.salary = :sal')
 ->setParameter('sal', $salary)
 ->andWhere('a.contract = :con')
 ->setParameter('con', $contract)
 ->andWhere('a.experience = :exp')
 ->setParameter('exp', $experience)
 ->andWhere('a.training = :tra')
 ->setParameter('tra', $training)
 ->orderBy('a.postedAt', 'DESC')
 ->getQuery()
 ->getResult()
 ;

in my controller :

public function index(Request $request, AdvertRepository $advertRepository): Response

 $form = $this->createForm(ResearchType::class);
 $form->handleRequest($request);

 if ($request->getMethod() == 'POST') 
 $salary = $form->get('salary')->getData();
 $contract = $form->get('contract')->getData();
 $experience = $form->get('experience')->getData();
 $training = $form->get('training')->getData();

 return $this->render('advert/index.html.twig', [
 'form' => $form->createView(),
 'adverts' => $advertRepository->findBySearchField(
 ['salary' => $salary],
 ['contract' => $contract],
 ['experience' => $experience],
 ['training' => $training]
 ),
 ]);
 

 return $this->render('advert/index.html.twig', [
 'form' => $form->createView(),
 'adverts' => $advertRepository->findAll(),
 ]);

I have an error "Notice: Undefined offset: 2"

However when I make this request in phpMyAdmin it returns what I am looking for

thank you for your feedback,
I found the solution, in my method findBySearchField I gave arrays instead of giving variables.
This solution works :

 public function index(Request $request, AdvertRepository $advertRepository): Response
 
 $form = $this->createForm(ResearchType::class);
 $form->handleRequest($request);

 if ($request->getMethod() == 'POST') 
 return $this->render('advert/index.html.twig', [
 'form' => $form->createView(),
 'adverts' => $advertRepository->findBySearchField(
 $salary = $form->get('salary')->getData(),
 $contract = $form->get('contract')->getData(),
 $experience = $form->get('experience')->getData(),
 $training = $form->get('training')->getData()
 ),
 ]);
 

 return $this->render('advert/index.html.twig', [
 'form' => $form->createView(),
 'adverts' => $advertRepository->findAll(),
 ]);
