Error details
I try to submit the modules but it returns fake error. It says the package are not created but I do and also with the same naming roles. Can you help me?
Well, I don’t know your error, but I can see that you have build and install and log directories inside the topics_quiz package. This means that you have wrongly compiled the package while inside the wrong directory. This can be causing confusion to the ROS system.
You need to delete those directories and then properly compile everything inside the ~/ros2_ws
