Exception thrown from ros_filter.cpp during launch in ROS2 galactic #674
Description
Bug report
Exceptions are thrown when running code in ROS2 galactic. I believe the reason is due to the change in the declaration of parameters, which in galactic all are given a specific type. Parameters that are not set with default values can therefore not be used to check if parameter values have been provided.
One example is on line 822-823 in ros_filter.cpp:
this->declare_parameterstd::string("tf_prefix");
if(this->get_parameter("tf_prefix", tf_prefix_path)) { ....
- Operating System:
Ubuntu 20.04 - Installation type:
Source - Version or commit hash:
galactic
Steps to reproduce issue
Build the code and launch e.g. dual_ekf_navsat_example.launch.py
Expected behavior
No exceptions thrown
Actual behavior
Exception: what(): expected [string] got [not set]
