Quiz - unit 4 - c++

Good afternoon, I have a problem with the self-correction of the quiz, it is not recognizing the signature of my code, and it is signing correctly, follow the attachment:

Hi Thales,

Welcome to the Community!

I apologize for this glitch. Let us look at what could be wrong and get back to you.

Hi Thales,

The problem was that you didn’t specify the expected name for the node - topics_quiz_node. The “examiner” is looking for that name in the subscribers list.

You specified that name alright in the C++ source code, but what you specified in the launch file, quiz, overrode that (by convention the node name specified in the launch file wins),

Now you know what to do :wink: .

I will also update the notes to make this clear.
