Can't make a MapSchema which value is a ArraySchema type

[y0unghe]

I am trying to make a map like below

{
  "id1": [
    new CardState(),
    new CardState(),
  ]
}

@type({ map: [CardState] })
playerHands = new MapSchema<CardState[]>();

But the error like

Argument of type '{ map: (typeof CardState)[]; }' is not assignable to parameter of type 'DefinitionType'.
  Types of property 'map' are incompatible.
    Type '(typeof CardState)[]' is not assignable to type 'PrimitiveType | (<U>(callbackfn: (value: PrimitiveType, index: number, array: PrimitiveType[]) => U, thisArg?: any) => U[])'.ts(2345)

Hi @y0unghe 👋 , this is not supported, for such relationship to work you'd need to have an intermediary Schema instance holding the array:

class Card extends Schema {
  // ...
}

class Hand extends Schema {
  @type([Card])
  cards = new ArraySchema<Card>();
}

class Player extends Schema {
  @type({ map: Hand })
  playerHands = new MapSchema<Hand>();
}
