Question about airflow-worker debugging

[sakaia]

Is there any method for debugging airflow-worker by helm installation?
In my environment, tutorial.py is works fine. but it failed on my test code on airflow run
but my test code works for airflow test.
From seeing, the log airflow-worker fails with pickle loading.

Loading pickle id %s 32
