Action Quiz: About the Result and Goal message

Hello, i am confused why we didnt declare the goal message, instead the result message is declared. The thing is the custom message only consists of feedback and the goal, no result.

(the one that I highlight)
And this is the custom msg for action;

Hi @sp_jason,
You can take a look at this for more detailed info:

With services and actions you always have a server and a client. The action client sends a goal, the action server responds with a result and feedback. If the result field is empty like it is in this example, it is defined just as that - Empty
