TYPO3 10.4.14 - 2021-04-02


When validating a controller’s argument, the following exception is thrown:

#1546632293 RuntimeException Could not get value of property "Site\Site\Domain\Model\Order::cart",
make sure the property is either public or has a getter getCart(), a hasser hasCart() or an isser isCart().

But there is a public function getCart(); defined in the class.


In Model, the property is nullable:

protected ?Cart $cart;

Add explicitly a default value:

protected ?Cart $cart = null;
