Symfony 5 pb with Repository

Question

I have the following error: DefinitionErrorExceptionPass.php line 54: Cannot autowire service "App\Repository\EmployeeRepository": argument "$entityClass" of method "Doctrine\Bundle\DoctrineBundle\Repository\ServiceEntityRepository::__construct()" has no type-hint, you should configure its value
explicitly.

My classes:

<?php
namespace App\Entity;

use Doctrine\ORM\Mapping as ORM;

/**
 * @ORM\Entity(repositoryClass="App\Repository\EmployeeRepository")
 */
class Employee extends User
{

}

Answer 1

The error is saying it already :

<?php

namespace App\Repository;

use App\Entity\Employee;
use Doctrine\Bundle\DoctrineBundle\Repository\ServiceEntityRepository;
use Doctrine\Common\Persistence\ManagerRegistry;

class EmployeeRepository extends ServiceEntityRepository {

    public function __construct(ManagerRegistry $registry) {
        parent::__construct($registry, Employee::class);
    }
    // Other code
}

Pass proper arguments to constructor as requierd as stated in docs. Querying for Objects: The Repository

The Error :

"Doctrine\Bundle\DoctrineBundle\Repository ServiceEntityRepository::__construct()" has no type-hint

As ServiceEntityRepository requires which entity type it belongs to, thus requiring type hinting by reference, we need to specify the class name to constructor.
