Issues with gradebot

@mackcom Welcome to the community! I apologize for the glitch and the frustration that resulted. Checking our logs, I see that you indeed scored 8/10 at some point, only missing the final point. Checking the final point does not behave as expected sometimes, and we are working on improving it. On that note, I checked your code and found that it achieved the objective of the quiz, so I have upgraded your score to 10/10. Regarding the /odom part that was failing later, I’m yet to figure out wh…

Good morning,
I am having the same issue with the gradebot, where gradebot repeatedly tells me the following:

Please check:

• Did you create a subscriber correctly to the topic /odom in your source code?
• Did you use the right node name? It should be topics_quiz_node

however, both issues are clearly resolved in the code and the robot ends up in the final position as requested.

Could you please look into the issue for me as I am running out of attempts.

Thanks,
Ghasef

The problem is that the /odom topic cannot be found when running your package:

ros2 topic info /odom -v
Unknown topic '/odom'

Please run the following commands and show us the output of both, after running the command in Terminal 2:

# Terminal 1
ros2 launch topics_quiz topics_quiz.launch.py

# Terminal 2
ros2 topic info /odom -v
