Problem visualizing in Rviz

[Cavalletta98]

Hi, i'm running ubuntu 20.04 with ROS Foxy and i'm not able to use Rviz for SLAM navigation.
I'm running the following commands on different terminals:

• ros2 launch jackal_gazebo jackal_world.launch.py
• ros2 launch jackal_navigation nav2.launch.py slam:=true use_sim_time:=true
• ros2 launch jackal_viz view_robot.launch.py
  For the command ros2 launch jackal_navigation nav2.launch.py slam:=true use_sim_time:=true, i'm getting this error [controller_server-2] [INFO] [1676476626.544682832] [local_costmap.local_costmap_rclcpp_node]: Message Filter dropping message: frame 'front_laser' at time 1581.062 for reason 'Unknown'.
  For the command ros2 launch jackal_viz view_robot.launch.py , i'm getting this warning [rviz2-1] Warning: Invalid frame ID "map" passed to canTransform argument target_frame - frame does not exist [rviz2-1] at line 133 in /tmp/binarydeb/ros-foxy-tf2-0.13.13/src/buffer_core.cpp and i'm not able to see the robot like in the picture atached
  
  
  Can you help me?

This issue of not seeing the information in rviz is due to your fixed frame being map which is not being published. Switch it to base_link and it will work.

It Is not normal that the map Is not published. Since i have to send a goal to the jackal,i should be in the map frame as fixed frame

Yes but rviz is behaving as expected when the frame is missing. #132 is the root cause.
