Error: JSON parse error: Unrecognized token

How to solve it?

I got success when using postman

Below is my datatables code

$('#userTable').DataTable({ 
    serverSide: true,
    ajax: { 
        url: api_url + '/api/v1/test',
        crossDomain : true,
        type : "POST",
        cache : false,
        dataType : "json",
        contentType: "application/json",
        dataSrc : "user",
        data: {
            "uid": "X123",
            "tokenid": "aasdkajf2324",
            "item": "user",
            "action": "read",
            "type": "1",
            "keyword": ""
        }
    },
    columns: [
        { data : "full_name", "className": "text-center" },
        { data : "userid", "className": "text-center" },
        { data : "level", "className": "text-center" }
    ],
});

First thing I'd say is to remove serverSide: true, since it doean't appear that you are actually using server-side processing (indeed, the Postman parameters don't include those that would have been sent by DataTables - the difference between client-side and server-side processing is discussed in the manual).

Beyond that - I'm not certain. Can you link to the page or a test case showing the issue so we can help resolve it please?

Thanks,

I just get the solution by this way

```JS
data: function(d) {
return JSON.stringify({"uid": "X123", "tokenid": "asdq4234", "item": "user", "action": "read", "type": "1", "keyword": "" });
}
