Livewire 3 - Property [$form.product_id] not found on component: [pages.ingredients-form-page]

Hello,

I get this strange error message (strange because all seems to be ok in my code, but sure something is wrong, but I don't see what).

Property [$form.product_id] not found on component: [pages.ingredients-form-page]

The form product_id property is used in the form page and is declared in the controller via a Livewire form.

#[Rule('required', message: 'Le produit est obligatoire.', onUpdate: false)]
public $product_id = null;

...

public IngredientForm $form;

...

<livewire:components.products-select wire:model="form.product_id"></livewire:components.products-select>

What am I doing wrong ?

Any idea ?

Thanks for your help.
