@rcangiano
What is the name you specified in your launch file and Python code? You have specified quiz_publisher somewhere. Please change that to topics_quiz_node and try again.

Also, please test your quiz before submitting and, next time, contact us after the 1st/2nd trail (and not the 4th!)

I had renamed with “topics_quiz_node” the executable but not the node name during creation, thank you.
