Hi @h90.rezaeifar

Did you trying to remove build, log and install before send to GradeBot? Usually works.

What is the output of ros2 node list, while launching your quiz package?

Thanks. Once, I changed the node name in my Python code to topics_node and forgot to return it to topics_quiz_node. Now it is working and I got 10/10.
