Slopes not working in Phaser using arcade physics

I'm currently having this issue when I am trying to get a sprite to go up a slope within phaser using the phaser-arcade-slopes.min.js plugin. I am using a .csv tilemap also with a tile size of 32x32. I'm unsure if my names are just incorrect or I am using the wrong type of file for the tilemap itself. I have been getting errors such as - Tilemap.createLayer: Invalid layer ID given: null & Cannot read property 'resizeWorld' of undefined(…). Any help would be much appreciated. "snow_tiles_32.png" is the name of the tileset I created and I'm using "tiles.csv" the tilemap created inside Tiled.

var game = new Phaser.Game(800, 600, Phaser.AUTO, '', { preload: preload, create: create, update: update });

function preload() {
this.game.load.tilemap('tilemap', 'assets/tilemaps/csv/tiles.csv', null, Phaser.Tilemap.CSV);
this.game.load.spritesheet('tiles', 'assets/tilemaps/tiles/snow_tiles_32.png', 32,32);
this.game.load.spritesheet('player', 'assets/penguin.png', 32,48);
}

var player;
var cursors;

function create() {
this.game.physics.startSystem(Phaser.Physics.ARCADE);
this.game.plugins.add(Phaser.Plugin.ArcadeSlopes);
cursors = game.input.keyboard.createCursorKeys();

this.map = this.game.add.tilemap('tilemap');
this.map.addTilesetImage('snow_tiles_32', 'tiles');

this.game.stage.backgroundColor = '#80e3ff';

this.ground = this.map.createLayer('collision');
this.ground.resizeWorld();

this.game.slopes.convertTilemapLayer(this.ground,{
    2:  'FULL',
    3:  'HALF_BOTTOM_LEFT',
    4:  'HALF_BOTTOM_RIGHT',
    6:  'HALF_TOP_LEFT',
    5:  'HALF_TOP_RIGHT',
    15: 'QUARTER_BOTTOM_LEFT_LOW',
    16: 'QUARTER_BOTTOM_RIGHT_LOW',
    17: 'QUARTER_TOP_RIGHT_LOW',
    18: 'QUARTER_TOP_LEFT_LOW',
    19: 'QUARTER_BOTTOM_LEFT_HIGH',
    20: 'QUARTER_BOTTOM_RIGHT_HIGH',
    21: 'QUARTER_TOP_RIGHT_HIGH',
    22: 'QUARTER_TOP_LEFT_HIGH',
    23: 'QUARTER_LEFT_BOTTOM_HIGH',
    24: 'QUARTER_RIGHT_BOTTOM_HIGH',
    25: 'QUARTER_RIGHT_TOP_LOW',
    26: 'QUARTER_LEFT_TOP_LOW',
    27: 'QUARTER_LEFT_BOTTOM_LOW',
    28: 'QUARTER_RIGHT_BOTTOM_LOW',
    29: 'QUARTER_RIGHT_TOP_HIGH',
    30: 'QUARTER_LEFT_TOP_HIGH',
    31: 'HALF_BOTTOM',
    32: 'HALF_RIGHT',
    33: 'HALF_TOP',
    34: 'HALF_LEFT'
});

this.map.setCollisionBetween(2,34, true, 'collision');

//player
this.player = this.game.add.sprite(100,50,'player');
this.game.physics.arcade.enable(player);

this.player.body.bounce.y = 0.2;
this.player.body.gravity.y = 2000;
this.player.body.collideWorldBounds = true;

this.player.animations.add('left', [0,1,2,3], 10, true);
this.player.animations.add('right', [5,6,7,8], 10, true);
this.game.slopes.enable(this.player);
this.game.camera.follow(this.player);

}

function update() {

this.game.physics.arcade.collide(this.player, this.ground);

this.player.body.velocity.x = 0;

if(cursors.left.isDown){
    this.player.body.velocity.x = -150;
    this.player.animations.play('left');
}
else if (cursors.right.isDown){
    this.player.body.velocity.x = 150;
    this.player.animations.play('right');
}
else{
    this.player.animations.stop();
    this.player.frame = 4;
}

if(cursors.up.isDown && player.body.onFloor()){
    this.player.body.velocity.y = -350;
}

}

LayerID you provide as parameter for createLayer() must match map layer defined in map file, see documentation. So my best guess would be to open map file in tiled once again and check what layer names you have.

Additionally there's example how to use .csv files (here)[http://phaser.io/examples/v2/tilemaps/csv-map].

Hope that'll help somehow.
