Próbuję przekazać wartość klucza i wygenerować odpowiedź JSON na podstawie przekazanego klucza

Program ekspresowy

var express = require('express'),
    async = require('async'),
    http = require('http'),
    mysql = require('mysql');

var app = express();

var connection = mysql.createConnection({
    host: 'localhost',
    user: 'root',
    password: "root",
    database: 'restaurants'
});

connection.connect();

// all environments
app.set('port', process.env.PORT || 7004);

app.get('/RestaurantDesc/', function (request, response, next) {

    var keyName = request.query.Key;
    var name_of_restaurants, RestaurantTimings;
    async.series([
        // Get the first table contents
        function (callback) {
            connection.query('SELECT * FROM ', keyName, function (err, rows, fields) {
                console.log('Connection result error ' + err);
                name_of_restaurants = rows;
                callback();
            });
        },
        // Get the second table contents
        function (callback) {
            connection.query('SELECT * FROM RestaurantTimings', function (err, rows, fields)

            {
                console.log('Connection result error ' + err);
                RestaurantTimings = rows;
                callback();
            });
        }
    // Send the response
    ], function (error, results) {
        response.json({
            'restaurants': name_of_restaurants,
                'RestaurantTimings': RestaurantTimings
        });
    });
});

app.get('/RestaurantDesc/', function (request, response, next) {

    var keyName = request.query.Key;
    var name_of_restaurants, RestaurantTimings;
    async.series([
    // Get the first table contents
    function (callback) {
        connection.query('SELECT * FROM ', keyName, function (err, rows, fields) {
            console.log('Connection result error ' + err);
            name_of_restaurants = rows;
            callback();
        });
    },
    // Get the second table contents
    function (callback) {
        connection.query('SELECT * FROM RestaurantTimings', function (err, rows, fields)

        {
            console.log('Connection result error ' + err);
            RestaurantTimings = rows;
            callback();
        });
    }

    // Send the response
    ], function (error, results) {
        response.json({
            'restaurants': name_of_restaurants,
                'RestaurantTimings': RestaurantTimings
        });
    });
});

http.createServer(app).listen(app.get('port'), function () {
    console.log('Express server listening on port ' + app.get('port'));
});

Testowe uruchomienie::

Dostaję odpowiedź JSON dla RestaurantTimings, ale nie pierwszą, w której przekazano wartość klucza, jak rozwiązać ten problem?
