Error: Packets out of order. Got: 0 Expected: 3 - mysql

Question

I'm using the MySQL module for NodeJS, however I keep getting the following error after approximately 10 requests to the database. I'm using the following code to connect to the DB:
var con = mysql.createConnection({
host: "10.37.100.15",
user: process.env.MYSQLUSR,
password: process.env.MYSQLPASSWD,
database: process.env.MYSQLDB
});
Then I use con.query(sqlStatement, function (err, result, fields) {<function>}). I already tried changing the max_allowed_packet to 500M on the server but this didn't fix the issue. This is the full error:
events.js:377
throw er; // Unhandled 'error' event
^

default wait_timeout is 8 hrs.
I'd suspect the mysql-nodejs version isn't resetting the expected packet count on re-connection.
In a test environment you can reduce the wait_timeout.
It quite possibly is:

Last comment on #2534 is "I change my connection from mysql.createConnection to mysql.createPool, the error never happen again"
