completely unrelated exception while saving many to many relationship doctrine and php - php

Question

so, I have multiple entities in my app, between them:
Product* - *Order
User* - 1UserRole
Order
class Order
{
...
/**
* #ManyToMany(targetEntity="Product", inversedBy="orders", cascade={"persist"})
* #JoinTable(
* name="orders_products",
* joinColumns={
* #JoinColumn(name="order_id", referencedColumnName="id")
* },
* inverseJoinColumns={
* #JoinColumn(name="product_id", referencedColumnName="id")
* }
* )
*/
private Collection $products;
...
public function __construct()
{
$this->products = new ArrayCollection();
}
...
public function addProduct(Product $product):self
{
$this->products[] = $product;
return $this;
}
}
Product
class Product
{
...
/**
* #ManyToMany(targetEntity="Order", mappedBy="products")
*/
protected Collection $orders;
...
public function __construct()
{
$this->orders = new ArrayCollection();
}
public function addOrder(Order $order): self
{
$this->orders[] = $order;
return $this;
}
}
User
class User
{
/**
* #ManyToOne(targetEntity="UserRole")
* #JoinColumn(name="role_id", referencedColumnName="id")
*/
protected $role;
}
And UserRole:
class UserRole
{
/** #Id #Column(type="integer") #GeneratedValue */
protected $id;
/** #Column(type="string", nullable=false, unique=true, length=20) */
protected $name;
/** #Column(type="integer", unique=true, nullable=false) */
protected $rolePriority;
/**
* Many Users have Many Stores.
* #ManyToMany(targetEntity="UserRoleAction", inversedBy="user_role_actions", fetch="EAGER", cascade={"persist"})
*/
protected Collection $userRoleActions;
/**
* UserRole constructor.
*/
public function __construct()
{
$this->userRoleActions = new ArrayCollection();
}
...
}
Ok so far, my issue is the following, when I try to save a new order that has many selected products:
class OrderService
{
public function createFromRequest(HttpRequest $request)
{
...
$products = $this->entityManager->getRepository(Product::class)->findWhatever(); //products are coming from this without issues.
foreach ($products as $product) {
$order->addProduct($product);
}
$this->entityManager->persist($order);
$this->entityManager->flush();
return $order;
}
}
I get:
Blockquote Expected value of type "UserRole" for association field "User#$role", got "__PHP_Incomplete_Class" instead.
I mean, how is this in any way related with the other entities??? I have no clue where to go to be fair. Any recommendations? Is doctrine doing some absolutely unrelated validation behind the scenes? wth?
