I am trying to send my tabulator row data to my server because i want to delete it from my database onClick of the distribute button but i cannot seem to figure that out. I have added a fetch function that should post to the specified express route which is not receiving that request. Someone kindly let me know how to solve this

Here is my script tag:

function btnFormatter( cell, params, onRendered ) {
    var element = document.createElement('button');
    var link = document.createElement('a')
    link.textContent = 'Distribute'
    link.className = "button-link"
    element.appendChild(link)
    
  
    onRendered( function() {
        element.addEventListener('click',()=>{
        var id = cell.getData().id
        const data = cell.getRow().getData()

        fetch('http://localhost:3000/delete/marketing', {
            method: 'POST',
            headers: {
                'Content-Type': 'application/json'
            },
            body: JSON.stringify(data)
        })
    })

    return element;
}

var table = new Tabulator(".table", {
    height:'auto', // set height of table (in CSS or here), this enables the Virtual DOM and improves render speed dramatically (can be any valid css height value)
    ajaxURL:'/marketing.json', //load data
    layout:"fitColumns", //fit columns to width of table (optional)
    columns:[ //Define Table Columns
        {title:"Customer Name", field:"name"},
        {title:"Commodity", field:"commodity",headerFilter:'input'},
        {title:"Quality", field:"quality",headerFilter:'input'},
        {title:"Quantity", field:"quantity"},
        {title:'Action',formatter:btnFormatter}
    ],
    // rowClick:function(e, row){ //trigger an alert message when the row is clicked
    //     alert("Row " + row.getData().id + " Clicked!!!!");
    // },
});

And my express route:

router.post('/delete/marketing',(req,res)=>{
    console.log(req.body)
    // connection.query('DELETE FROM order_table WHERE id = ?', req.body.id,(error,results)=>{
    //     if(error){
    //         console.log('error')
    //     } else {
    //         console.log('item deleted')
    //     }
    // })
})
