Bug introduced by
Accessing parent_id on the interface hiqdev\yii2\cart\CartPositionInterface suggest that you code against a concrete implementation. How about adding an instanceof check?

If you access a property on an interface, you most likely code against a concrete implementation of the interface.

Available Fixes

  1. Adding an additional type check:

    interface SomeInterface { }
    class SomeClass implements SomeInterface {
        public $a;
    }
    
    function someFunction(SomeInterface $object) {
        if ($object instanceof SomeClass) {
            $a = $object->a;
        }
    }
    
  2. Changing the type hint:

    interface SomeInterface { }
    class SomeClass implements SomeInterface {
        public $a;
    }
    
    function someFunction(SomeClass $object) {
        $a = $object->a;
    }

Bug introduced by
The method hasErrors() does not seem to exist on object<hiqdev\yii2\cart\CartPositionInterface>.

This check looks for calls to methods that do not seem to exist on a given type. It looks for the method on the type itself as well as in inherited classes or implemented interfaces.

This is most likely a typographical error or the method has been renamed.
