I have recently update to ROS2 dashing and I have the issue that when I run my nodes with ros2 run I see the messages typed inside node.get_logger().info('') but when I launch the same node from a launch file using ros2 launch [package] [launch_file] it does not (just appears the message [INFO] [nodename-1]: process started with pid [xx]).

My current launch file is the following one:

# ROS imports
from launch import LaunchDescription
from launch_ros.actions import Node


def generate_launch_description():
    ld = LaunchDescription([
        Node(package='gui_pkg', node_executable='gui_node', output='screen'),
        Node(package='sequence_scheduler_pkg', node_executable='sequence_scheduler_node', output='screen'),
        Node(package='planner_pkg', node_executable='planner_node', output='screen'),
        Node(package='simulation_pkg', node_executable='simulation_node', output='screen'),
        Node(package='dds_wrapper_pkg', node_executable='Action2DDSCudaGps', output='screen'),
        Node(package='state_machine_pkg', node_executable='state_machine_node', output='screen')
    ])
    return ld


if __name__ == '__main__':
    generate_launch_description()

I know that the common mistake is to forget the screen but I am not and it is strange that in CRYSTAL it works while in DASHING doesn´t.

What it is even more strange is that if I cancel the execution with Ctr+C I see all the messages like they were always there from before
