The problem is that in the Spryker core the interface was moved to another module (

shipment-extension

), but the plugin misses to implement the new interface and a fallback in the old interface is missing for backward compatibility. You can report this bug to Spryker via their support portal, as they do not actively read bugs here. For a fast solution, extend the

OnlyGiftCardShipmentMethodFilterPlugin

in your project, add the

Spryker\Zed\ShipmentExtension\Dependency\Plugin\ShipmentMethodFilterPluginInterface

to it and replace the usage in

ShipmentDependencyProvider::getMethodFilterPlugins()

to use the one you just create in your project
