node mysql cannot access property - mysql

Question

Having some trouble parsing the results returned from a node "mysql" query.
Node version 7.8.0
Running CentOS AWS environment.
I developed the node app in Windows Visual Studio CE 2017, and it was working fine, but when porting it to Linux, it's not actually allowing me to access the user_id variable within the results.
I have included lots of variations in trying to access the variable, however the correct one I believe should be:
rows[i].user_id
All the others are just there as a reference to show that they don't work.
Code:
'use strict';
var express = require('express');
var router = express.Router();
var bodyParser = require('body-parser');
var mysql = require("mysql");
var con = mysql.createConnection(dbConfig);
con.connect(function (err) {
if (err) {
console.log('Error connecting to Db');
return;
}
console.log('Connection established');
});
var q = "select * from table";
con.query(q, function (err, rows) {
for (var i = 0; i < rows.length; i++) {
var row = JSON.stringify(rows[i]);
var rowParsed = JSON.parse(row);
console.log(row);
console.log(" row[0].user_id " + row[0].user_id );
console.log(" row.user_id " + row.user_id );
console.log(" parsed " + JSON.parse(row));
console.log(" rowParsed.user_id " + rowParsed.user_id);
console.log(" rowParsed['user_id'] " + rowParsed['user_id']);
console.log(" rows[i].user_id " + rows[i].user_id)
console.log(" rows[i]['user_id'] " + rows[i]['user_id']);
console.log(rows[i]);
}
});
Results:
Connection established
[{"user_id":2}]
parsed [object Object]
row[0].user_id undefined
row.user_id undefined
rowParsed.user_id undefined
rowParsed['user_id'] undefined
rows[i].user_id undefined
rows[i]['user_id'] undefined
[ RowDataPacket { user_id: 2 } ]
