Duplicating a cart price rule returns an error

[the-line]

When a cart price rule is duplicated, an error is given. The rule is also not duplicated.

What we noticed is that in the file /vendor/leat/magento2-loyalty/src/module-loyalty/Plugin/SalesRule/ExtensionAttributesPlugin.php at the function beforeSave, there is a call to $rule->getData('gift_skus'). This method does not exist on the given interface. This might break compatibility with other modules, like in this example. This is the reason this error is returned.

The callstack is:
