IntegrityError：使用Praw在Python中数据类型不匹配

我正在尝试编写一个带“ fuck”一词的reddit机器人，看看有多少人在reddit上这么说。这是代码：

import praw
import time
import re
import sqlite3

username = "LewisTheRobot"
password = "lewismenelaws"

conn = sqlite3.connect('reddit')
c = conn.cursor()
r = praw.Reddit(user_agent = "Reddit bot")

word_to_match = [r'\bfuck\b', r'\bfucking\b', r'\bfucks\b']

storage = []

r.login(username, password)

def run_bot():
    subreddit = r.get_subreddit("all")
    print("Grabbing subreddit!")
    comments = subreddit.get_comments(limit=200)
    print("Grabbing comments!")
    for comment in comments:
        comment_text = comment.body.lower()
        isMatch = any(re.search(string, comment_text) for string in word_to_match)
        if comment.id not in storage and isMatch and comment.author not in storage:
            print("We have found a fuck boy. Storing username: " + str(comment.author) + "into database.")
            storage.append(comment.author)
            c.execute("INSERT INTO users (id, Username, subreddit, comment) VALUES(?,?,?,?)", (str(comment.id), str(comment.author), str(comment.subreddit), str(comment.body)))
            conn.commit()

    print("There are currently " + str(len(storage)) + " fuck boys on reddit at the moment.")



while True:
    run_bot()
    time.sleep(2)

每当我运行该漫游器时，只要找到匹配项并给我这个错误，它都会崩溃。

据我了解，这意味着数据库中的某些内容不是正确的数据类型，无法插入我的数据库。我很确定这是str(comment.body)SQL设置的一部分。我的SQLITE数据库具有注释字段作为文本字段。谢谢您的帮助。

这是数据库浏览器中显示的数据库凭据。
