Handle's typesupport identifier (rosidl_typesupport_c) is not supported by this library [galactic]

[russkel]

Describe the bug

I have followed the tutorial https://micro.ros.org/docs/tutorials/core/first_application_linux/ and when it comes time to run the MicroROS agent and the ping_pong demo, I am getting this error:

[russ@sherlock microros_ws]$ ros2 run micro_ros_demos_rclc ping_pong

>>> [rcutils|error_handling.c:108] rcutils_set_error_state()
This error state is being overwritten:

  'Handle's typesupport identifier (rosidl_typesupport_c) is not supported by this library, at /tmp/binarydeb/ros-galactic-rosidl-typesupport-c-1.2.1/src/type_support_dispatch.hpp:113'

with this new error message:

  'Undefined type support, at /home/russ/Devel/ros/microros_ws/src/uros/rmw_microxrcedds/rmw_microxrcedds_c/src/rmw_publisher.c:127'

rcutils_reset_error() should be called after error handling to avoid this.

I have replicated the tutorial and it works as expected: https://asciinema.org/a/4dhLRFdPu0VusGKeQoWDwKEu3

Can you check that you are using the commands correctly?

Weird. I will try it again.

Is this error:

'Handle's typesupport identifier (rosidl_typesupport_c) is not supported by this library, at /tmp/binarydeb/ros-galactic-rosidl-typesupport-c-1.2.1/src/type_support_dispatch.hpp:113'

Because the typesupport should be rosidl_typesupport_microxrcedds_c instead? Is that the problem here?

Thanks for testing it @pablogs9

I guess that it is related to your ROS 2 installation, can you test this inside a docker with a clean ROS 2 installation?

I rm'ed build and install dirs and then ran build firmware/build agent again, and that seems to have fixed it. No idea what happened. Thanks for that and sorry for the waste of time.
