Steps to reproduce issue

I downloaded ros2.repo from ros2 master branch, and the commit id of launch is given above. After i compiled ros2, i tested a simple launch.py which can be executed sucessfully in crystal release. Below is my launch.py:

import os
from launch import LaunchDescription
import launch.actions
import launch_ros.actions


def generate_launch_description():
    map_yaml_file = launch.substitutions.LaunchConfiguration('map', default="asdf")

    return LaunchDescription([
        launch_ros.actions.Node(
            package="param_test",
            node_executable="set_and_get_parameters",
            node_name="set_and_get_parameters",
            node_namespace="",
            output="screen",
            parameters=[{'map_file': map_yaml_file}]
        ),
        launch_ros.actions.Node(
            package="param_test",
            node_executable="access_other_node_parameters",
            node_name="access_other_node_parameters",
            node_namespace="",
            output="screen",
        )
    ])

Then i got this error:

TypeErorr: get_default_launch_description() got an unexpected keyword argument 'prefix_output_with_name'

Expected behavior

no error
