[Python] Error 'Failed to import plugin opt/airflow/plugins/operatos/. . . ' when running...

In my project, I build a docker image on my local machine, then pull the image to the production machine. On my local machine, I can still run the image using the docker-compose up command to create a container.

But on the production machine, I get an error message in logs:

{plugins_manager.py:305} ERROR - Failed to import plugin /opt/airflow/plugins/operators/name.py
airflow-init | Traceback (most recent call last):
airflow-init | File "/home/airflow/.local/lib/python3.10/site-packages/airflow/plugins_manager.py", line 298, in load_plugins_from_plugin_directory

airflow-init | File "/opt/airflow/plugins/operators/name.py", line 33, in <module>
airflow-init | from helper1.task_logger import TaskRunMetadata
airflow-init | ModuleNotFoundError: No module named 'helper1'


On both machines I have the same docker library configuration, I also copied all the configuration files to the product machine just in case. The plugin files in that path still exist. I don't know why it says Failed to import plugin

Thanks for your help.
