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 AppBundleEntity;

use ApiPlatformCoreAnnotationApiResource;
use DoctrineORMMapping as ORM;


/**
 * Foo
 *
 * @ORMTable(name="foo")
 * @ApiResource
 * @ORMEntity
 */
class Foo
{
    /**
     * @var string
     *
     * @ORMColumn(name="bar", type="string", length=255, nullable=false)
     */
    private $bar;

    /**
     * @var integer
     *
     * @ORMColumn(name="id", type="integer")
     * @ORMId
     * @ORMGeneratedValue(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!

Answer

You’re missing a getter for your id

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