Wanting to launch this command ros2 launch br_test_canopen_config motor_controllers_ros_control.launch.py
And get this error : [INFO] [launch]: All log files can be found below /home/u20/.ros/log/2023-05-22-16-02-54-208338-u20-VirtualBox-222822 [INFO] [launch]: Default logging verbosity is set to INFO Task exception was never retrieved future: <Task finished name='Task-2' coro=<LaunchService._process_one_event() done, defined at /opt/ros/galactic/lib/python3.8/site-packages/launch/launch_service.py:226> exception=SubstitutionFailure("executable '[<launch.substitutions.text_substitution.TextSubstitution object at 0x7fb6bf6d8640>]' not found on the PATH")> Traceback (most recent call last): File "/opt/ros/galactic/lib/python3.8/site-packages/launch/launch_service.py", line 228, in _process_one_event await self.__process_event(next_event) File "/opt/ros/galactic/lib/python3.8/site-packages/launch/launch_service.py", line 248, in __process_event visit_all_entities_and_collect_futures(entity, self.__context)) File "/opt/ros/galactic/lib/python3.8/site-packages/launch/utilities/visit_all_entities_and_collect_futures_impl.py", line 45, in visit_all_entities_and_collect_futures futures_to_return += visit_all_entities_and_collect_futures(sub_entity, context) File "/opt/ros/galactic/lib/python3.8/site-packages/launch/utilities/visit_all_entities_and_collect_futures_impl.py", line 45, in visit_all_entities_and_collect_futures futures_to_return += visit_all_entities_and_collect_futures(sub_entity, context) File "/opt/ros/galactic/lib/python3.8/site-packages/launch/utilities/visit_all_entities_and_collect_futures_impl.py", line 45, in visit_all_entities_and_collect_futures futures_to_return += visit_all_entities_and_collect_futures(sub_entity, context) [Previous line repeated 2 more times] File "/opt/ros/galactic/lib/python3.8/site-packages/launch/utilities/visit_all_entities_and_collect_futures_impl.py", line 38, in visit_all_entities_and_collect_futures sub_entities = entity.visit(context) File "/opt/ros/galactic/lib/python3.8/site-packages/launch/action.py", line 108, in visit return self.execute(context) File "/opt/ros/galactic/lib/python3.8/site-packages/launch_ros/actions/node.py", line 465, in execute self._perform_substitutions(context) File "/opt/ros/galactic/lib/python3.8/site-packages/launch_ros/actions/node.py", line 420, in _perform_substitutions evaluated_parameters = evaluate_parameters(context, self.__parameters) File "/opt/ros/galactic/lib/python3.8/site-packages/launch_ros/utilities/evaluate_parameters.py", line 164, in evaluate_parameters output_params.append(evaluate_parameter_dict(context, param)) File "/opt/ros/galactic/lib/python3.8/site-packages/launch_ros/utilities/evaluate_parameters.py", line 72, in evaluate_parameter_dict evaluated_value = perform_substitutions(context, list(value)) File "/opt/ros/galactic/lib/python3.8/site-packages/launch/utilities/perform_substitutions_impl.py", line 26, in perform_substitutions return ''.join([context.perform_substitution(sub) for sub in subs]) File "/opt/ros/galactic/lib/python3.8/site-packages/launch/utilities/perform_substitutions_impl.py", line 26, in return ''.join([context.perform_substitution(sub) for sub in subs]) File "/opt/ros/galactic/lib/python3.8/site-packages/launch/launch_context.py", line 232, in perform_substitution return substitution.perform(self) File "/opt/ros/galactic/lib/python3.8/site-packages/launch/substitutions/command.py", line 94, in perform command_str = perform_substitutions(context, self.command) File "/opt/ros/galactic/lib/python3.8/site-packages/launch/utilities/perform_substitutions_impl.py", line 26, in perform_substitutions return ''.join([context.perform_substitution(sub) for sub in subs]) File "/opt/ros/galactic/lib/python3.8/site-packages/launch/utilities/perform_substitutions_impl.py", line 26, in return ''.join([context.perform_substitution(sub) for sub in subs]) File "/opt/ros/galactic/lib/python3.8/site-packages/launch/launch_context.py", line 232, in perform_substitution return substitution.perform(self) File "/opt/ros/galactic/lib/python3.8/site-packages/launch/substitutions/path_join_substitution.py", line 45, in perform performed_substitutions = [sub.perform(context) for sub in self.__substitutions] File "/opt/ros/galactic/lib/python3.8/site-packages/launch/substitutions/path_join_substitution.py", line 45, in performed_substitutions = [sub.perform(context) for sub in self.__substitutions] File "/opt/ros/galactic/lib/python3.8/site-packages/launch/substitutions/find_executable.py", line 66, in perform raise SubstitutionFailure("executable '{}' not found on the PATH".format(self.name)) launch.substitutions.substitution_failure.SubstitutionFailure: executable '[<launch.substitutions.text_substitution.TextSubstitution object at 0x7fb6bf6d8640>]' not found on the PATH
