"Treasure Hunter" Exercise; bug or did I do something wrong?


I am currently taking a course for game development here on codecademy. Right now I am working on a project called “Treasure Hunter”. I am on a step where I am making all the spaces in the grid to appear blank. To do this, I am making plot to be blank, and pushing that onto the grid.

// Create your global variables here
let plot;
let grid = [];
let coinCollection = [];
let playerCoins = 0;
let compCoins = 0;

class GameScene extends Phaser.Scene {
    constructor() {
        key: 'GameScene'

    preload() {
      // We have preloaded our images such as the background, the coins, the digging image etc.
      this.load.image('board', 'https://codecademy-content.s3.amazonaws.com/courses/learn-phaser/Treasure+Hunter/Gameboard+Default.png', {
        frameWidth: 240,
        frameHeight: 320
      this.load.image('gold', 'https://codecademy-content.s3.amazonaws.com/courses/learn-phaser/Treasure+Hunter/gold+coin.png');
      this.load.image('playerGold', 'https://codecademy-content.s3.amazonaws.com/courses/learn-phaser/Treasure+Hunter/gold+coin+shine.png');
      this.load.image('dig', https://codecademy-content.s3.■■■■■■■■■■■■■■■■■■■■■■■■■■■■■■■■■■■■■■■■■■■■■■■■■■■■■■■■■■■.png');
      this.load.image('blank', 'https://codecademy-content.s3.amazonaws.com/courses/learn-phaser/Treasure+Hunter/blank.png'); // These are the actual images / tiles that load on top of 'board'

    create() {
      // The background is provided below
      this.add.sprite(240, 320, 'board');
      // Create the for loops to create the grid
       for (let x = 46; x < 437; x += 78) {
        for (let y = 46; y < 437; y += 78){
          plot = this.add.sprite(x, y, 'blank');
      // Create the coins from the grid created above  
      // Create the function which decides the coin locations here 
      } // End of Create

Supposedly, ‘blank’ is supposed to bring a blank image. However, what I am getting is this;

I failed to see what I am doing wrong, so I used the solution code from codecademy; it still is showing that error image.

What’s going on here?

BTW, the “dig” image is loading fine; idk why it looks that way on this post


I am experiencing the same issue - have been trying for 30 minutes to fix it but cannot see why it wouldn’t work given the URL is correct and other images work in it’s place…

I am going to move on and see if anything appears here about it.
