Cannot assign Symfony\Component\VarDumper\Caster\CutStub to reference held by property App\Entity\AccountName::$accountType

I am developing a project by Symfony 6.2. In this project one entity AccountType with many to one relationship another entity AccountCategory.

#[ORM\Entity(repositoryClass: AccountTypeRepository::class)]
class AccountType
{
#[ORM\Id]
#[ORM\GeneratedValue]
#[ORM\Column]
private ?int $id = null;
#[ORM\Column(length: 255)]
private ?string $name = null;
#[ORM\Column(length: 255)]
private ?string $code = null;
#[ORM\Column(length: 255, nullable: true)]
private ?string $remarks = null;
#[ORM\OneToMany(mappedBy: 'accountType', targetEntity: AccountName::class)]
private Collection $accountNames;
#[ORM\ManyToOne(inversedBy: 'accountTypes')]
#[ORM\JoinColumn(nullable: false)]
private ?AccountCategory $accountCategory = null;
public function __construct()
{
$this->accountNames = new ArrayCollection();
}
public function getId(): ?int
{
return $this->id;
}
public function getName(): ?string
{
return $this->name;
}
public function setName(string $name): self
{
$this->name = $name;
return $this;
}
public function getCode(): ?string
{
return $this->code;
}
public function setCode(string $code): self
{
$this->code = $code;
return $this;
}
public function getRemarks(): ?string
{
return $this->remarks;
}
public function setRemarks(?string $remarks): self
{
$this->remarks = $remarks;
return $this;
}
/**
* @return Collection<int, AccountName>
*/
public function getAccountNames(): Collection
{
return $this->accountNames;
}
public function addAccountName(AccountName $accountName): self
{
if (!$this->accountNames->contains($accountName)) {
$this->accountNames->add($accountName);
$accountName->setAccountType($this);
}
return $this;
}
public function removeAccountName(AccountName $accountName): self
{
if ($this->accountNames->removeElement($accountName)) {
// set the owning side to null (unless already changed)
if ($accountName->getAccountType() === $this) {
$accountName->setAccountType(null);
}
}
return $this;
}
public function getAccountCategory(): ?AccountCategory
{
return $this->accountCategory;
}
public function setAccountCategory(?AccountCategory $accountCategory): self
{
$this->accountCategory = $accountCategory;
return $this;
}
}

Another Entity:

#[ORM\Entity(repositoryClass: AccountCategoryRepository::class)]
class AccountCategory
{
#[ORM\Id]
#[ORM\GeneratedValue]
#[ORM\Column]
private ?int $id = null;
#[ORM\ManyToOne(inversedBy: 'accountCategories')]
#[ORM\JoinColumn(nullable: false)]
private ?AccountReport $accountReport = null;
#[ORM\Column(length: 255)]
private ?string $name = null;
#[ORM\Column(length: 255)]
private ?string $code = null;
#[ORM\Column(length: 555, nullable: true)]
private ?string $remarks = null;
#[ORM\OneToMany(mappedBy: 'accountCategory', targetEntity: AccountType::class)]
private Collection $accountTypes;
public function __construct()
{
$this->accountTypes = new ArrayCollection();
}
public function getId(): ?int
{
return $this->id;
}
public function getAccountReport(): ?AccountReport
{
return $this->accountReport;
}
public function setAccountReport(?AccountReport $accountReport): self
{
$this->accountReport = $accountReport;
return $this;
}
public function getName(): ?string
{
return $this->name;
}
public function setName(string $name): self
{
$this->name = $name;
return $this;
}
public function getCode(): ?string
{
return $this->code;
}
public function setCode(string $code): self
{
$this->code = $code;
return $this;
}
public function getRemarks(): ?string
{
return $this->remarks;
}
public function setRemarks(?string $remarks): self
{
$this->remarks = $remarks;
return $this;
}
/**
* @return Collection<int, AccountType>
*/
public function getAccountTypes(): Collection
{
return $this->accountTypes;
}
public function addAccountType(AccountType $accountType): self
{
if (!$this->accountTypes->contains($accountType)) {
$this->accountTypes->add($accountType);
$accountType->setAccountCategory($this);
}
return $this;
}
public function removeAccountType(AccountType $accountType): self
{
if ($this->accountTypes->removeElement($accountType)) {
// set the owning side to null (unless already changed)
if ($accountType->getAccountCategory() === $this) {
$accountType->setAccountCategory(null);
}
}
return $this;
}
}

When data retrieve for editing of Account Type form then shown below error.

"Cannot assign Symfony\Component\VarDumper\Caster\CutStub to reference held by property App\Entity\AccountCategory::$accountReport of type ?App\Entity\AccountReport"

Seems to be an issue related to php version. I had the same issue and just upgrade my php to 8.2 and the issue disapears.
