amcl is clock being publish

edit

Hi,

Im trying to use the amcl package for localization. Everything is doing fine except that when I use the command

$ rostopic echo /amcl_pose

the output is WARNING: no messages received and simulated time is active.

I have already use the commands:

  <rosparam name="/use_sim_time" value="true"/>
  <node name="rosbag" pkg="rosbag" type="play" 
        args=" --clock $(find amcl)/2020-01-29-11-19-28.bag"/>

In my launch file and when I write rostopic list the topic /clock is being publish so I don't undestand the message error. Can somebody help me. Any help is appreciated!
