Interesting issue when using ProjectionParams::FromConfigFile method

[berkay1]

We created a config file for VLP32C. Using FromConfigFile method, we were able to run algorithm but if point cloud topic is not present at the moment when show_objects_node started, then it doesnt subscribe to the topic. I debugged it with rosnode info, terminal output gives nonnumeric port error and can not contact to node. How is this possible? If I use ProjectionParams::HDL32, I can contact to node. What can affect it in this way?

Forget what I said. I fixed the issue and it is not related to this repo.
