I have an application created by the advanced template, with frontend, backend and console applications.
Now I would like to add rest API to the application and under frontend/controller folder I created a new folder called api where I stored some new controllers that inherits from yii\rest\Controller.
All works fine except when the client make the preflight check with OPTIONS request to the controller and it returns always a 404 error.
Could you help me to understand what’s missing in your opinion?
How Yii manage those options requests?
