After /submit_task, the /task_list shows an empty list, and the task_id on topic /fleet_states do not match the one from /submit_task

[rubenanapu]

Hi all,

when I submit a task using https://open-rmf.github.io/rmf-panel-js/ I get a task_id, something like: demos_cff3ebac-9b42-48c5-a3e5-7cec237f693d

But if I try to list the tasks by pressing the REFRESH button on the Tasks area of https://open-rmf.github.io/rmf-panel-js/, I get an empty list.

After enabling JavaScript Developers Console, I see it calls http://localhost:8083/task_list, which always returns an empty list, even when I have a Delivery task running. If I send another task right away, it also still shows an empty list.

When I check the fleet_states topic with ros2 topic echo /fleet_states, I can see the robot, but the task_id is always an integer, something like task_id: '155'. I can never see the ID that appears when calling /submit_task.

Does anybody know how to make the /fleet_states show the id returned by /submit_task?

What am I really trying to do?

What I'm really trying to do is to show the list of finished, waiting, and running tasks in a dashboard, but these IDs that don't match and the empty list on /task_list are not helping, and that is why I started this discussion.

Please feel free to correct me if I misunderstand something.

Hello @rubenanapu! Are you perhaps referring to the success snack bar that appears in the panel, saying something along the lines of Request submitted successfully! Task ID: .....?

Thanks for bringing this up, unfortunately rmf-panel-js is not actively being maintained, and has quite a number of legacy features and concepts, including the generation of such uuids. These uuids are created by the dispatcher_client from rmf_demos_panel, https://github.com/open-rmf/rmf_demos/blob/main/rmf_demos_panel/rmf_demos_panel/dispatcher_client.py#L96.

I would recommend switching over the our web dashboard, https://github.com/open-rmf/rmf-web, which we are actively developing, where the task IDs are accurately reflected (same as from /fleet_states), and the task statuses are up to date too.

Hi @aaronchongth,

that is right. The demos_cff3ebac-9b42-48c5-a3e5-7cec237f693d Task ID I was referring to is exactly the one that appears in the success snack bar.

Thank You very much for pointing me to Web Dashboard (https://github.com/open-rmf/rmf-web)

I'll mark this discussion closed then. If necessary, I open it again.

Once again, thank you very much. May God bless you.
