Issue running Apache-airflow SnowflakeOperator tutorial example - airflow

Question

Trying to get a simplified version snowflake operator example to work, but triggering the DAG fails with error:
Task exited with return code Negsignal.SIGABRT
The dag only has the 1st task running the CREATE_TABLE_SQL_STRING. It will run successfully via test run: airflow dags test sf_example_short 2021-10-10
I can see the table is created in snowflake so connection appears fine and syntax must be okay.
But drop the table and trigger via airflow UI or via CLI:
airflow dags trigger sf_example_short it fails w/vague error:
Task exited with return code Negsignal.SIGABRT
googling I’ve found suggestions to change scheduler_health_check_threshold, or schedule_after_task_exectution, or default_impersonation, or OBJC_DISABLE_INITIALIZE_FORK_SAFETY, or killed_task_cleanup_time
but none of these fixed the issue
What am I missing? TIA!
