ROS1 Bridge not working.

[pranavs1911]

I tried to run ROS1 Bridge using the examples given in the README page. However, there still seems to be some communication issue when I run the dynamic bridge node. A video is attached for reference.

When I was slightly suspicious that RTPS was provoking the issue, I followed the steps in https://answers.ros.org/question/394404/rtps_transport_shm-error-and-at-the-same-time-no-topics-are-available-in-ros2-topic-list/

after which I observed the following:
rmw_fastrtps_shared_cpp = 1.3.2
rmw_fastrtps_cpp = 1.3.2

Any leads on this problem would be appreciated. Thanks
