[Bug] Grade checker throwing error on /turn service

Error details

The grade checker is throwing an error on /turn service even when the service is listed with ros2 service list. Earlier on it compiled fine past this check but on the next try it failed. This is rather frustrating given that the advice it gives sometimes is not accurate. I do not know if you can handle instances like these.

Hello @kaayatheophilus ,

For this kind of issue related to the GradeBot, it would be very helpful if you provide the output of the Gradebot (maybe sharing an image of it here). I would suggest you try the following:

1. Remove the current build files:

cd ~/ros2_ws 
rm -rf build install log

2. Send again to the GradeBot.

Let me know if this fixes your issue.
