Why is the data not being entered into the table?

Question

Python

Throws an error when executing the code

Ignoring exception in command warns:
Traceback (most recent call last):
  File "C:\Users\roman\AppData\Local\Programs\Python\Python38-32\lib\site-packages\discord\ext\commands\core.py", line 85, in wrapped
    ret = await coro(*args, **kwargs)
  File "bot.py", line 558, in __warns
    userwarns = cursor.execute("SELECT warns FROM users WHERE id = {}".format(member.id)).fetchone()[0]
TypeError: 'NoneType' object is not subscriptable

The above exception was the direct cause of the following exception:

Traceback (most recent call last):
  File "C:\Users\roman\AppData\Local\Programs\Python\Python38-32\lib\site-packages\discord\ext\commands\bot.py", line 903, in invoke

There is no data with this id in the table, but why?

The code itself:

cursor.execute("""CREATE TABLE IF NOT EXISTS users (
        name TEXT,
        id INT,
        cash BIGINT,
        rep INT,
        lvl INT,
        warns INT,
        exp BIGINT,
        exp2 BIGINT,
        allexp BIGINT
    )""")
    for guild in client.guilds:
        for member in guild.members:
            if cursor.execute(f"SELECT id FROM users WHERE id = {member.id}").fetchone() is None:
                cursor.execute(f"INSERT INTO users VALUES ('{member}', {member.id}, 0, 0, 1, 0, 0, 0, 0)")
                connection.commit()
            else:
                pass
