type mismatch between tRPC return (in sveltekit) and defined type

i've got this piece of code: ```ts read: async () => { const res = await trpc($page).getCards.query(); if (!res) return; cards = cards_reducer(cards, { type: 'reload', payload: { cards: res } }); }, ``` the issue is that the type of res, as returned from trpc, is `SerializeObject >[]`, while i've type my cards state as `(Card & { tasks: Task[]; })[];`. as far as i can tell, there should be no mismatch in type here, but the linter isn't happy with trying to pass `res` as the same type as `cards`

i've got this piece of code:

read: async () => {
  const res = await trpc($page).getCards.query();

  if (!res) return;

  cards = cards_reducer(cards, {
    type: 'reload',
    payload: { cards: res }
  });
},

read: async () => {
  const res = await trpc($page).getCards.query();

  if (!res) return;

  cards = cards_reducer(cards, {
    type: 'reload',
    payload: { cards: res }
  });
},

the issue is that the type of res, as returned from trpc, is

SerializeObject<UndefinedToOptional<Card & { tasks: Task[]; }>>[]

SerializeObject<UndefinedToOptional<Card & { tasks: Task[]; }>>[]

, while i've type my cards state as

(Card & { tasks: Task[]; })[];

(Card & { tasks: Task[]; })[];

. as far as i can tell, there should be no mismatch in type here, but the linter isn't happy with trying to pass

res

res

as the same type as
