Почему ошибка sqlite3.ProgrammingError?

База данных:

import sqlite3

class SQLighter:

    def __init__(self, database):
        self.connection = sqlite3.connect(database)
        self.cursor = self.connection.cursor()

    def subscriber_exists(self, user_id):
        with self.connection:
            result = self.cursor.execute('SELECT * FROM `subscriptions` WHERE `user_id` = ?', (user_id,)).fetchall()
            return bool(len(result))

        with self.connection:
            return self.cursor.execute("UPDATE `subscriptions` SET `status` = ? WHERE `user_id` = ?", (status, user_id))
