Closing a newly-created cursor throws

[batterseapower]

Expected behavior

When you do this:

conn = trino.dbapi.connect(...)
cur = conn.cursor()
cur.close()

The close should succeed.

Actual behavior

The close actually fails:

trino.exceptions.OperationalError: Cancel query failed; no running query

Steps To Reproduce

conn = trino.dbapi.connect(...)
cur = conn.cursor()
cur.close()

Log output

Traceback (most recent call last):
  File "<stdin>", line 1, in <module>
  File ".../python3.10/site-packages/trino/dbapi.py", line 709, in close
    self.cancel()
