Unable to generate an IRI for the item of type App\\Entity\\User

[Marko1212]

I have created an API using Symfony 6 and API Platform 3. For the first entities, everything went fine but I have an error now when I am doing a GET collection request for User entity (end point : api/users) :

Unable to generate an IRI for the item of type \"App\\Entity\\User\"

So why this happens and how to fix it ?

Here is an excerpt from my User entity :

#[ApiResource(

operations: [
    new Delete(),
    new Get(),
    new Put(),
    new Patch(),
    new GetCollection(),
    new Post()
],
normalizationContext: ['groups' => ['read:User']]
)]
#[ApiFilter(OrderFilter::class)]
#[ORM\Entity(repositoryClass: UserRepository::class)]
class User
{

#[ORM\Id]
#[ORM\Column(unique: true, nullable: false, type: 'string')]
#[Groups(groups: ['read:User'])]
#[ApiProperty(identifier: true)]
private $username;

#[ORM\OneToOne(mappedBy: 'user', cascade: ['all'])]
#[Groups(groups: ['read:User'])]
private ?Employee $employee = null;

#[ORM\Column(name: 'first_name', length: 255, nullable: true)]
#[Groups(groups: ['read:User'])]
private ?string $firstName = null;

#[ORM\Column(name: 'last_name', length: 255, nullable: true)]
#[Groups(groups: ['read:User'])]
private ?string $lastName = null;

#[ORM\OneToMany(mappedBy: 'username', targetEntity: UserRole::class, cascade: ['all'], orphanRemoval: true)]
#[Groups(groups: ['read:User'])]
private Collection $userRoles;

#[ORM\Column(length: 2000, nullable: true)]
private ?string $password = null;

public function __construct()
{
    $this->userRoles = new ArrayCollection();
}

public function getUsername(): string
{
    return $this->username;
}

public function setUsername(string $username): self
{
    $this->username = $username;
    return $this;
}

Thanks in advance!

This fixes the issue :

#[ApiResource(
    operations: [
        new Delete(uriTemplate: 'users/{username}'),
        new Get(uriTemplate: 'users/{username}'),
        new Put(uriTemplate: 'users/{username}'),
        new Patch(uriTemplate: 'users/{username}'),
        new GetCollection(uriTemplate: 'users'),
        new Post(uriTemplate: 'users')
    ],
...
]
