 /**

public function searchProduit(Request $request,NormalizerInterface $Normalizer)

{

    $repository = $this->getDoctrine()->getRepository(Produit::class);

    $requestString=$request->get('searchValue');

    $products = $repository->findProduitByName($requestString);

    $jsonContent = $Normalizer->normalize($products, 'json',['groups'=>'products']);

    $retour = json_encode($jsonContent);

    return new Response($retour);

My Answer:
The issue of getting undefined data in the AJAX response could be due to a few reasons. Here are some possible solutions to resolve this issue:

1. Check the AJAX request:
Make sure that the AJAX request is sending the correct data to the Symfony controller. You can use console.log() in the AJAX request to log the data being sent and verify if it is correct.

2. Check the Symfony controller:
Ensure that the searchValue parameter is being correctly retrieved from the request. You can use var_dump() or dump() to debug and check the value of $requestString.

3. Check the findProduitByName() method:
Verify that the findProduitByName() method in the repository is correctly querying the database and returning the expected results. You can also check if the $products variable is being populated with the correct data.

4. Check the normalization process:
Make sure that the normalization process is working correctly and converting the $products data into a JSON format. You can debug this process by checking the value of $jsonContent before encoding it to JSON.

By following these steps and debugging each part of the code, you should be able to identify the issue causing the undefined data result in the AJAX response.
