Make Code Arcade Arrays(?) Uncaught e.findIdx is not a function

I am working on a Microsoft Make Code Arcade Game in VS code using the Microsoft MakeCode Arcade Extension. While attempting to make enemies spawn automatically via a for loop, I ran into an error.

VS Code error msg:

    Uncaught e.findIdx is not a function
       at lvl1 (main.ts:105:1)
       at inline (main.ts:54:57)

Make Code Arcade Website error msg:

    e.findIdx is not a function

I believe this is caused by the array I was trying to use to create the variables for the sprites. But I do not know for sure.

Section of code Causing the problem:

    let enemys: any = []
    let enemyNumber: number
    for (let i: number = 0; i < 3; i++) {
        // enemy setup
        enemyNumber = i
        enemys[enemyNumber] = sprites.create(assets.image`Basic Enemy`, SpriteKind.Enemy)
        enemys[enemyNumber].vx = -30
    
        // enemy movment setup
        game.onUpdateInterval(200, function () { // evry 0.2 sec          
            if (enemys[enemyNumber].vx == 30) {  // if the player is traveling right
                if (!    (tiles.tileAtLocationIsWall(enemys[enemyNumber].tilemapLocation().getNeighboringLocation(CollisionDirection.Right).getNeighboringLocation(CollisionDirection.Bottom)))) { // if the tile to the below and to the right of the sprite is not a wall
                    enemys[enemyNumber].vx = -30 // make the sprite turn the other direction
                }
            } else {
                if (!        (tiles.tileAtLocationIsWall(enemys[enemyNumber].tilemapLocation().getNeighboringLocation(CollisionDi    rection.Left).getNeighboringLocation(CollisionDirection.Bottom)))) { // if the tile to the below and     to the right of the sprite is not a wall
                    enemys[enemyNumber].vx = 30 // make the sprite turn the other direction
                }
            }
        })
    }
    
    tiles.placeOnTile(enemys[1], tiles.getTileLocation(10, 14))
    tiles.placeOnTile(enemys[2], tiles.getTileLocation(20, 14))
    tiles.placeOnTile(enemys[3], tiles.getTileLocation(29, 11))

The git-hub repo can be found here. The Branch I am working on is called Code-(Colton) and can be found here. The error is caused in main.ts

I tried to comment out lines 115-135, but the error persisted. This may mean that something is a pre-defined asset, but I am verry lost. I do not know what the error message is telling me.

The error was caused by an incorrect definition of the array type. To solve this in Make Code, you simply chang the type to Sprite[] so make code knows the contet of the array is going to be sprites.

line one should now read: let basicenemys: Sprite[] = []

Though, after this another error presents itself. in some locations, make code does not recognize the item in the array as a sprite, or existing. I am loking into this, but will not elaberate furthure on this thread.
