当我试图在我的表中插入数据时，我得到了这个错误“connect econnrejued 127.0.0.1:2543”下面是我的nodejs代码我正在使用postman测试我的api

app.post("/interaction", async (req, res) => {
    try {
        const { fname } = req.body.fname;
        const { lname } = req.body.lname;
        const { email } = req.body.email;
        const { password } = req.body.password;

        const text =
            "INSERT INTO userdetails (fname, lname, email, password) VALUES ($1, $2, $3, $4)";
        const values = [fname, lname, email, password];
        const dataEntry = await pool.query(text, values);
    } catch (error) {
        console.log(error.message);
    }
});
