Bug introduced by
It seems like you code against a concrete implementation and not the interface Sylius\Component\Resourc...el\TranslationInterface as the method getName() does only exist in the following implementations of said interface: Sylius\Component\Attribu...el\AttributeTranslation, Sylius\Component\Core\Model\ProductTranslation, Sylius\Component\Payment...aymentMethodTranslation, Sylius\Component\Product...ociationTypeTranslation, Sylius\Component\Product...uctAttributeTranslation, Sylius\Component\Product...roductOptionTranslation, Sylius\Component\Product\Model\ProductTranslation, Sylius\Component\Product...oductVariantTranslation, Sylius\Component\Shippin...ippingMethodTranslation, Sylius\Component\Taxonomy\Model\TaxonTranslation.

Let’s take a look at an example:

interface User
{
    /** @return string */
    public function getPassword();
}

class MyUser implements User
{
    public function getPassword()
    {
        // return something
    }

    public function getDisplayName()
    {
        // return some name.
    }
}

class AuthSystem
{
    public function authenticate(User $user)
    {
        $this->logger->info(sprintf('Authenticating %s.', $user->getDisplayName()));
        // do something.
    }
}

In the above example, the authenticate() method works fine as long as you just pass instances of MyUser. However, if you now also want to pass a different implementation of User which does not have a getDisplayName() method, the code will break.

Available Fixes

  1. Change the type-hint for the parameter:

    class AuthSystem
    {
        public function authenticate(MyUser $user) { /* ... */ }
    }
    
  2. Add an additional type-check:

    class AuthSystem
    {
        public function authenticate(User $user)
        {
            if ($user instanceof MyUser) {
                $this->logger->info(/** ... */);
            }
    
            // or alternatively
            if ( ! $user instanceof MyUser) {
                throw new \LogicException(
                    '$user must be an instance of MyUser, '
                   .'other instances are not supported.'
                );
            }
    
        }
    }
    
Note: PHP Analyzer uses reverse abstract interpretation to narrow down the types inside the if block in such a case.
  1. Add the method to the interface:

    interface User
    {
        /** @return string */
        public function getPassword();
    
        /** @return string */
        public function getDisplayName();
    }
