Error details
I can launch the file on my own just fine, but gradebot can not. It's about little quiz at Topics. I can test the program just fine, I see it working. But when I use grade bot it gives me 3/10 unable to launch the file.
This can happen if you did not create the package according to the specifications. Gradebot grades your package according to those specifications.
From the logs, it seems your topics_quiz depends on another package, mars_rover_tasks. While gradebot is running, other packages within the workspace are not visible. You can check this requirement by running the following commands
cd ~/ros2_ws
rm -rf build/ install/ log/
colcon build --packages-select topics_quiz
source install/setup.bash
ros2 launch topics_quiz topics_quiz.launch.py
