I am trying to override `Magento\Eav\Api\Data\AttributeOptionInterface` in my custom module. I want to add one new option to existing interface. The idea behind is, As of now we can only pass defined options data in attribute options **REST API** **See below API request format for more clarity.** **Api** Url = http://test.com/index.php/rest/V1/products/attributes/manufacturer/options/ Api Methodd - Post Api body - { "option": { "label": "test", "is_default": "true", } } **As of now its passing 3 parameters as value, I want to add my custom 4th parameters Ex - Slider.** So parameters should be { "option": { "label": "test", "is_default": "true", "slider":"test1" } } **I have tried to override interface and its method but its giving property setter not defined** **Error Message** "message": "Property \"Slider\" does not have corresponding setter in class \"Magento\\Eav\\Api\\Data\\AttributeOptionInterface\"." So here my question is how can I override API interface and pass my custom or add my option in existing parameters. Hope it makes sense, your help will be appreciated. Thanks.
