Missing hydra:total items in api - php

Question

I'm currently having an issue I do not manage to explain.
I have a symfony/api-platform entity defined like this:
namespace App\Entity;
use ApiPlatform\Core\Annotation\ApiFilter;
use ApiPlatform\Core\Annotation\ApiResource;
use ApiPlatform\Core\Bridge\Doctrine\Orm\Filter\ExistsFilter;
use Doctrine\Common\Collections\ArrayCollection;
use Doctrine\Common\Collections\Collection;
use Doctrine\ORM\Mapping as ORM;
use Doctrine\ORM\Mapping\JoinColumn;
use Doctrine\ORM\Mapping\ManyToOne;
use Doctrine\ORM\Mapping\OneToMany;
use Symfony\Component\Serializer\Annotation\Groups;
/**
* #ORM\Entity
* #ApiResource(
* normalizationContext={"groups"={"node_read"}},
* denormalizationContext={"groups"={"node_write"}},
* collectionOperations={
* "get"={"method"="GET"},
* "post"={"method"="POST", "security"="is_granted('ROLE_ADMIN')"}
* },
* itemOperations={
* "get"={"method"="GET"},
* "put"={"method"="PUT", "security"="is_granted('ROLE_ADMIN')"},
* "patch"={"method"="PATCH", "security"="is_granted('ROLE_ADMIN')"},
* "delete"={"method"="DELETE", "security"="is_granted('ROLE_ADMIN')"}
* }
* )
* #ApiFilter(ExistsFilter::class, properties={"parent"})
*/
class Node
{
/**
* #ORM\Id()
* #ORM\GeneratedValue()
* #ORM\Column(type="integer")
* #Groups({"node_read"})
*/
private ?int $id;
/**
* #ORM\Column(type="string", length=255)
* #Groups({"node_read", "node_write"})
*/
private string $key;
/**
* #ORM\Column(type="string", length=255)
* #Groups({"node_read", "node_write"})
*/
private string $label;
/**
* #ORM\Column(type="string", length=255)
* #Groups({"node_read", "node_write"})
*/
private string $type;
/**
* One Category has Many Categories.
*
* #OneToMany(targetEntity="Node", mappedBy="parent")
* #Groups({"node_read"})
*/
private Collection $children;
/**
* Many Nodes have One Node.
*
* #ManyToOne(targetEntity="Node", inversedBy="children")
* #JoinColumn(name="parent_id", referencedColumnName="id")
* #Groups({"node_write"})
*/
private ?Node $parent;
/**
* #ORM\Column(type="string", nullable=true)
*/
private string $description;
public function __construct()
{
$this->children = new ArrayCollection();
}
public function getId(): ?int
{
return $this->id;
}
public function getParent(): ?Node
{
return $this->parent;
}
public function setParent(?Node $parent): self
{
$this->parent = $parent;
return $this;
}
public function getChildren(): Collection
{
return $this->children;
}
public function setChildren(Collection $children): self
{
$this->children = $children;
return $this;
}
public function getKey(): string
{
return $this->key;
}
public function setKey(string $key): self
{
$this->key = $key;
return $this;
}
public function getLabel(): string
{
return $this->label;
}
public function setLabel(string $label): self
{
$this->label = $label;
return $this;
}
public function getType(): string
{
return $this->type;
}
public function setType(string $type): self
{
$this->type = $type;
return $this;
}
public function getDescription(): string
{
return $this->description;
}
public function setDescription(string $description): self
{
$this->description = $description;
return $this;
}
}
While making a get call on the collection, I have different results between development environment and production.
In the prod env, the api is missing a hydra metadata key hydra:total.
Results in dev env :
context: "/api/contexts/Node"
#id: "/api/nodes"
#type: "hydra:Collection"
hydra:member: [{#id: "/api/nodes/1", #type: "Node", id: 1, key: "risk-of-rain-2", label: "Risk Of Rain 2",…},…]
hydra:totalItems: 2
hydra:view: {#id: "/api/nodes?exists%5Bparent%5D=false", #type: "hydra:PartialCollectionView"}
hydra:search: {#type: "hydra:IriTemplate", hydra:template: "/api/nodes{?exists[parent]}",…}
results in prod env :
#id: "/api/nodes"
#type: "hydra:Collection"
hydra:member: [{#id: "/api/nodes/12", #type: "Node", id: 12, key: "feedback", label: "Feedback", type: "Game",…},…]
hydra:view: {#id: "/api/nodes?exists%5Bparent%5D=false", #type: "hydra:PartialCollectionView"}
hydra:search: {#type: "hydra:IriTemplate", hydra:template: "/api/nodes{?exists[parent]}",…}
As you can see in prod I am missimg the key hydra:totalItems: 2 which allows me to make react-admin work.
I have compared both project composer dependency and PHP version and prod is ISO to dev env.

Answer 1

I found my issue which was not related at all with the provided source code but with deployment.
Rsync did not remove deleted file of the project and I had an overridding Dataprovider.
Solution was to use --delete option in rsync command.
