How to create multiple complex sqlite transactions with an expected out using apsw?

I want to execute several complex statements in a transaction with a select statement at the end which I use for further processing.

Doing so once works fine but as soon as I execute the same statement again it causes the error below.

Test code:

import apsw
connection = apsw.Connection("temp.db")

cursor = connection.cursor()
cursor.execute("""
BEGIN TRANSACTION;
CREATE TABLE Foo(x);
COMMIT;
""")

cursor = connection.cursor()
print(cursor.execute("""
BEGIN TRANSACTION;
INSERT INTO Foo (x) VALUES (1);
INSERT INTO Foo (x) VALUES (2);
SELECT x FROM Foo LIMIT 1;
COMMIT;
""").fetchone())


cursor = connection.cursor()
print(cursor.execute("""
BEGIN TRANSACTION;
INSERT INTO Foo (x) VALUES (3);
INSERT INTO Foo (x) VALUES (4);
SELECT x FROM Foo LIMIT 1;
COMMIT;
""").fetchone())

Output:

$ python test.py 
(1,)
Traceback (most recent call last):
  File "test.py", line 28, in <module>
    """).fetchone())
  File "src/cursor.c", line 236, in resetcursor
apsw.SQLError: SQLError: cannot start a transaction within a transaction

Edit: It seems to be connected to the “fetchone()” method, if I instead use “fetchall()” it works. In my specific case I do expect on one result, so I have edited the code to reflect this.
