我一直收到错误消息“error：运算符不存在：text = bigint”。任何建议都会有帮助！谢谢。如果你知道如何检查令牌是否存在，那也会很有帮助，因为我正在传递它。下面是我的代码：

const  bcrypt  =  require("bcrypt");

const  client  =  require("../configs/database");

const  jwt  =  require("jsonwebtoken");

exports.updateemail  =  async (req, res) => {
    const { 
        id,
        newemail,
        cid
    } =  req.body;

    const query = "UPDATE users SET (email) = ("+newemail+") WHERE id = "+id+" AND cid = "+cid+"";

    try {
        const res = await client.query(query)
        res.status(200).send({ message: 'Success' });
    } catch (err) {
        console.log(err.stack)
        return false;
    }
}
