action feedback type creating a new type action feedback message after creating a new client

edit

I am using navigtion2 stack and want to get just feedback for the goal separately along with the traditional client which returns response,feedback and result. The action name is "navigate_to_pose" . So, I created another simple client with the same action name to print the feedback messages from this link https://docs.ros.org/en/foxy/Tutorial... . However, I am not able to get any output on the terminal. I am able to retrieve the feedback information using ros2 topic echo /{topic_name}.

The problem I am facing with the simple client I have written is: once I publish a goal, I am able to do ros2 topic echo /navigate_to_pose/_action/feedback and get the feedback data printed on terminal. But if I start the simple client simultaneously, I get an error message for ros2 topic echo /navigate_to_pose/_action/feedback

Error message: Cannot echo topic '/navigate_to_pose/_action/feedback', as it contains more than one type: [nav2_msgs/action/NavigateToPose_Feedback, nav2_msgs/action/NavigateToPose_FeedbackMessage].

The following are some of screenshots. Please help me out
