Run it through JSON.stringify so you are logging a single string and not a complex data structure.

as say here How can I get the full object in Node.js's console.log(), rather than '[Object]'?

you can convert your element (object or array) directly in json by using

console.log('my elem : %j', myObject);

or if you want more display option, you can use util.inspect

const util = require('util')
console.log(util.inspect(myObject, {showHidden: false, depth: null, colors: true}))

You can use

 console.dir(myArry, {'maxArrayLength': null});

The console method log() displays the toString representation of any object passed to it. The Console method dir() displays an interactive list of the properties of the specified JavaScript object
