Unable to use node.launch file in ros2 foxy

[tadteo]

I'm trying to use mavros in ROS2 (in a docker container forked from the ros foxy docker images). I have installed mavros from the deb package ros-foxy-mavros.

However, when trying to run the node.launch file I have an error about a syntax error or an unknown format of the launch file.

The detailed error is the following:

$ ros2 launch mavros node.launch

future: <Task finished name='Task-2' coro=<LaunchService._process_one_event() done, defined at /opt/ros/foxy/lib/python3.8/site-packages/launch/launch_service.py:226> exception=InvalidLaunchFileError('')>

MAVROS version and platform

Mavros: ros2
ROS: Foxy
Ubuntu: 20.04 (on docker)

What could it be? How can we solve it? Is some tag not supported in ROS2?

I installed mavros foxy through apt, no docker
