SyntaxError: "[object Object]" is not valid JSON
    at <anonymous>:6:16
    at mn (<anonymous>:16:5455)

you need to use JSON.stringify() method first, then parse the data to JSON object

const message = {"code":"200","msg":"Sample movement recorded succsfully"} 

var obj = JSON.stringify(message);
var msg = JSON.parse(obj);
// Log to console
console.log(msg.msg)
