mysql - 类型错误 : Cannot read property 'Symbol(asyncId)' of null

Question

我有一个基于node.js的express服务器，它应该处理一些数据库操作。目前，我尝试根据提供的电子邮件获取我的 SQL 数据库的一些信息。在执行下面的操作时，我遇到了一个奇怪的错误。

app.get("/character/:account_email", jsonparser, (req, res) => {
    database.query("SELECT account_email, character_name, creation_date, blood, money, experience_points, age, is_alive, place_name FROM vmpr_character WHERE account_email = ?", [req.params.account_email], (error, response, fields) => {
        res.set({ "Content-Type": "application/json" });
        if (!error) {
            res.status(201);
            res.write(JSON.stringify(response[0]));

            database.query("SELECT attribute_name, level FROM character_attributes JOIN vmpr_character USING (account_email) WHERE character_attributes.account_email = ?", [req.params.account_email], (error2, response2, fields2) => {
                if (!error2) {
                    res.write(JSON.stringify(response2));
                } else {
                    res.status(502);
                }
            });
        } else {
            res.status(404);
            res.write(JSON.stringify(dummy));
        }
        res.end();
    });
});

将某些数据发布到同一数据库时会发生相同的错误。服务器在 POST 和 GET 上都会崩溃，即使提供的数据仍然正常保存。在 mysql 中执行这些查询直接得到正确的结果。所有日志都很好。

编辑:* 通过提供的更新，错误消失了，新的错误更好处理。* 现在一切都很好。谢谢!
