[ROS2] Cannot add parameter to ros2 control

edit

In my .xacro file, I am adding ros2 control with the following snippet:

<gazebo>
    <plugin filename="libgazebo_ros2_control.so" name="gazebo_ros2_control">
      <parameters>$(find auto_park)/config/controllers.yaml</parameters>
    </plugin>
</gazebo>

When I run the following commands to launch the simulation:

source /opt/ros/humble/setup.bash
ros2 launch auto_park launch_sim.launch.py

I receive the following error:

Caught exception in launch (see debug for traceback): substitution args not supported:  No module named 'roslaunch'

If I remove the snippet where ros2 control is added, the simulation is able to launch. Any idea what might be the issue?

The following is controllers.yaml:

controller_manager:
  ros__parameters:
    update_rate: 30
    use_sim_time: true

    diff_drive_controller:
      type: diff_drive_controller/DiffDriveController

    joint_state_broadcaster:
      type: joint_state_broadcaster/JointStateBroadcaster

diff_drive_controller:
  ros__parameters:
