Data Received from frontend is not getting updated in database

Question

//React Js (frontend) Code

function onclickcancel(){
        setdate('0000-00-00')
        settime('00:00:00')
        settopic('Cancelled')

        axios.put('http://localhost:8081/cancel',{email,date,time,topic})
        .then(res=>{
            console.log("Interview Cancelled")
            seterr("Interview Cancelled")
        })
        .catch(error=> console.log(error))
    }



// Node JS (backend) code 

//Interview Cancel

app.put('/cancel',async(req,res)=>{
    const {email,date,time,topic} = req.body
    
    const sql = "update users SET `Date` = ?, `Time` = ?, `Topic` = ? where Email = ?"

    db.query(sql,[date,time,topic,email],(error,data)=>{
        if (error){
            return res.json(error)
        }
        return res.json(data)
    })
})

Here, I am Sending date =('0000-00-00') time=('00:00:00')topic = ('Cancelled') to backend but this data is not getting stored in my database

date =('0000-00-00') time=('00:00:00')topic = ('Cancelled') this data should update in db when i click cancel
