Hi. I took a look at your code and in the Player class this is your function:

constructor(name,id,color,active= false) {
    //other properties
    this.token=this.createTokens(21);
}
get unusedTokens(){
    return this.tokens.filter(token => !token.dropped);
}

I think the problem is that you have a token property, but you're trying to filter using this.tokens. You probably need to change your property to this: this.tokens=this.createTokens(21);
