I am calling ros2 param list and get back: Exception while calling service of node '/node_name': None for all 3 nodes I have. How can I show these exceptions?

While not an answer to my problem I found out that the different middlewares are incompatible. So setting export RMW_IMPLEMENTATION=rmw_fastrtps_cpp before using ros2 param list fixed my problem and I got the list of params.
