I don't know why I keep failing the test for task 1a in the bascis_exam. However, when I run roslaunch bascis_exam drone_off.launch alone, the drone can take off normally. May I ask what the reason is?

Error details
[17:43:37] [assess] /dist_motion_service result message was NOT correct.
When I call the service myself through the terminal, the result matches the requirement. However, I still can’t pass the assessment test. Could you please tell me what’s wrong?
The problem was that your service did not return a response, as it should. According to the logs:
ERROR: service [/dist_motion_service] returned no response
It appears one of the topics we use for checking drone takeoff was not working. Sorry about that. We can give you the full points for this while looking into the problem, but you need to work on the /dist_motion_service part.
