Cannot enqueue Handshake after invoking quit

Question

I have implemented the following code:

module.exports = {
    getDataFromUserGps: function(callback)
    {
        connection.connect();
        connection.qu

SOLUTION: to prevent this error(for AWS LAMBDA):

In order to exit of "Nodejs event Loop" you must end the connection, and then reconnect. Add the next code to invoke the callback:

connection.end( function(err) {
        if (err) {console.log("Error ending the connection:",err);}

       //  reconnect in order to prevent the"Cannot enqueue Handshake after invoking quit"

         connection = mysql.createConnection({
                host     : 'rds.host',
                port     :  3306,
                user     : 'user',
               password : 'password',
               database : 'target database'

               });
        callback(null, {
            statusCode: 200,
            body: response,

        });
    });
