I get malformed launch argument ‘simple_topic_subscriber.launch.py’, expected format’:=’ when I am in the folder ~/ros2_ws/src.
In other folders I get the following: Package ‘topic_subscriber_pkg’ not found: "package ‘topic_subscriber_pkg’ not found, searching
I have sourced my workspace with source ~/ros2_ws/install/setup.bash and I have also activated rosbridge but I cannot solve this problem
