When i try to change debug_mode to false

[sunnyhello3696]

The error occurred after I changed the debug_mode to False in arena-rosnav/arena_bringup/configs/training/training_config.yaml:

<=======================>

I'm looking at the printout and guessing that the reason might be because the robot.launch file fails to start at line 222 of arena-rosnav/task_generator/task_generator/manager/robot_manager.py.
I can't fix it!

Actually, earlier, when debug_mode=true, I've tried to fix a lot of minor bugs, including
1, Incongruous errors from version updates in planners/rosnav/scripts/rosnav_node.py.
2, incorrect paths to the launch file when testing other Planners, and other Planners that don't run or don't test well(include:crowdnav、all-in-one .etc)
3、When full_range_laser= true, the network input dimension reports an error
...
Some of the above problems I can fix myself and some I'm not so good at (although it has taken a lot of effort)

Please help me, I'm limited in my ability to work out these bugs on my own, I won't be able to graduate [cry].
