api platform - Unable to generate an IRI for the item

I'm starting with API Platform and I'm using the example entity "Foo":

namespace AppBundle\Entity;

use ApiPlatform\Core\Annotation\ApiResource;
use Doctrine\ORM\Mapping as ORM;


/**
 * Foo
 *
 * @ORM\Table(name="foo")
 * @ApiResource
 * @ORM\Entity
 */
class Foo
{
    /**
     * @var string
     *
     * @ORM\Column(name="bar", type="string", length=255, nullable=false)
     */
    private $bar;

    /**
     * @var integer
     *
     * @ORM\Column(name="id", type="integer")
     * @ORM\Id
     * @ORM\GeneratedValue(strategy="IDENTITY")
     */
    private $id;


}

I succesfully see the new Entity in dashboard (See image):

API Platform Dhasboard

And I had the following error when I try to get all Foo collection:

curl -X GET "http://127.0.0.1:8000/foos" -H "accept: application/json"

    {
  "type": "https://tools.ietf.org/html/rfc2616#section-10",
  "title": "An error occurred",
  "detail": "Unable to generate an IRI for the item of type \"AppBundle\\Entity\\Foo\"",
  "trace": [
    {
      "namespace": "",
      "short_class": "",
      "class": "",
      "type": "",
      "function": "",
      "file": "/home/xxxx/api/vendor/api-platform/core/src/Bridge/Symfony/Routing/IriConverter.php",
      "line": 107,
      "args": []
    },

I tried different formats and check the the routes too:

 ------------------------------- -------- -------- ------ -----------------------------------

It's possible what I need some special library in my server? What I'm doing wrong?

Thanks in advance!

For future visitors; the PHP 8.4 property hooks also seem to result in this error on the creation of a resource.

#[ORM\Id]
#[ORM\Column(type: 'integer')]
#[ORM\GeneratedValue(strategy: 'SEQUENCE')]
private ?int $id = null {
    get {
        return $this->id;
    }
}

The probable cause is that the ORM can not hydrate the freshly created object with the persistence layer's newly generated identifier after flush, but will not make the request throw an exception either.

interesting that it seems like it's obligatory to add get word in getter, so you can't have id() but getId()

Adding an answer as it may help other people, I had a typo in my uriTemplate parameter, and used {format} instead of {_format} which caused the $this->router->generate to fail in vendor/api-platform/core/src/Symfony/Routing/IriConverter.php.

    uriTemplate: '/users/{user_id}/subresource.{_format}',

To debug this, comment the try/catch in the IriConverter.php class to see the exact error.

I met this issue during the implementation of "API Platform + ElasticSearch".

Debugged the exception I found more clearer explanation: "Not able to retrieve identifiers. Unable to generate an IRI for the item of type "App\Entity\..."

In my case entity didn't have a setId() method.

public function setId(int $id): void
{
    $this->id = $id;
}

It has helped me.

I was passing for a similar problem, and I was having a big difficulty to find a solution.

Just to help someone that couldn't find some answer, I suggest going deeper and put some debug/dump inside the IriConverter class to see what is really happening.

I discovered that my main class was ok, but another a relation/linked class had a problem. So sometimes could be in another place but with the same error.

For future visitors:

You'll get this error allways if you disable json-ld format. Check your configuration file ./config/packages/api_platform.yaml:

formats:
        json:     ['application/json']
        jsonld:   ['application/ld+json']
        jsonapi:  ['application/vnd.api+json']
        html:     ['text/html']
        csv:      ['text/csv']

This error can be launched for several reasons. Other one happens when you declare an entity without ORM and you forgot declare its ItemDataProvider

Remove your existing entity and create new model with bin/console make:entity has worked for me !

You're missing a getter for your id

public function getId()
{
    return $this->id;
}
