Invalid SessionHandle: SessionHandle error

[Bidek56]

I am creating engine with pool_pre_ping=True

create_engine(f"databricks://token:{token}@{host}?http_path=sql/protocolv1/o/{org_id}/{cluster_id}", pool_pre_ping=True, echo_pool=True)

But after a some inactivity time I get: sqlalchemy.exc.DatabaseError: (databricks.sql.exc.DatabaseError) Invalid SessionHandle: SessionHandle error. which tells me pool_pre_ping=True is not being used. How can I check if pool_pre_ping=True is used? Thx
