Simulator shuts down in headless mode + Python API after 30 seconds

[t0ny-peng]

This is similar but slightly different to #1396 so I'm opening a new issue.

The comfig.yml I'm using is:

headless: true
read_only: false
api_hostname: "*"
api_port: 8181
cloud_url: "https://wise.svlsimulator.com"

The simulation profile in the website is 52c9044a-090a-426e-a169-db7ab8f70b14(if you can read from the backend). Basically it's in headless mode, with Python API and Autoware.Auto (Apex.AI).

After I clicked Run simulation, the window did turn into a 3D map with a car(is it real headless mode?), and I can control the car with keyboard. However, no matter what I do, it alway shuts down after 30 seconds and go back to the original window(dark blue background with two rose-color buttons) and the status in the website goes back to idle.

Is there a log that I can upload to help debug? Thanks

Yes, please look for the player.log here

Hi I have experienced close/shutdown in simulator, always when I runned the Python Api with AutowareAi AD Stack for the reason below:

• I forgot to run//activate the Ros-Bridge before starting the simulation. You must always activate on runtime manager the TAB maps and MAINLY the TAB SENSING, which launch the websocket bridge. Otherwise the Simulator will be closed with the warning: "Websocket was unexpectedly closed" or similar.

I have also used Autoware.Auto and this shutdown failure occurred for 2 reasons:

1- when the ROS bridge in configure json Tab was not properly defined, or some . json sensor configuration was wrong

2- When I have not launched the ros2-web-bridge on terminal or ros2-lgsvl-bridge. I forgot which bridge worked better. However months ago I tested both and they worked. I have never tested the Python Api with Autoware.Auto, but I feel that this error is more related to the bridge setup than the Python Api functionality.
I cannot evaluate your log file unfortunately as I am just a student user as you.

I hope it works for you.
