Question Unity ml agents was stop training after it execute.

Hello, I have a problem about unity mlagent. My environment is agent try to escape the room by press the button and moving to the exit. Everything doing well so far. However, when I create trainer_config.yaml to adjust the hyperparameter, I can execute `mlagents-learn \{config.yaml path} --run-id=test` but then when I press play button on Unity it start training for a second and then stop. I got the error message here "mlagents.trainers.exception.TrainerConfigError: The behavior name Roll agent has not been specified in the trainer configuration. Please add an entry in the configuration file for Roll agent, or set default_settings." And this is my tool version
ML agents: 2.0.1 - November 08, 2021
PyTorch: 1.11.0
Editor version 2021.3.8f1
I have no idea how to fix this problem
