[Question] Issue with zustand-slices types using no store actions

[jeremiahfallin]

I have several slices that have objects as values. I am getting the error:

Element implicitly has an 'any' type because expression of type 'any' can't be used to index type '{ selectedCharacter: string | null; characters: { [characterId: string]: Character; }; locationCharacterIndex: { [locationId: string]: Set<string>; }; }'.

On the state.characters[characterId]; in this slice/action:

import { createSliceWithImmer } from "zustand-slices/immer";
import useStore from "./useStore";
import { transferItems } from "./characterSlice";

interface Notification {
  id: string;
  message: string;
  type: "success" | "error";
}

export const processCollectAction = (
  characterId: any,
  item: string,
  quantity: number | "max"
) =>
  useStore.setState((state) => {
    const character = state.characters[characterId];
    transferItems(character.location, character.id, item, quantity, true);
    state.characters[characterId].currentAction = { type: "idle" };
    return state;
  });

const storageSlice = createSliceWithImmer({
  name: "storage",
  value: { gameTime: 0 },
  actions: {
    incrementGameTime: () => (state) => {
      state.gameTime += 1;
    },
  },
});

export default storageSlice;

And the relevant excerpt from the character slice:

const characterSlice = createSliceWithImmer({
  name: "characters",
  value: {
    selectedCharacter: null as string | null, // No character is selected by default
    characters: {
      ...createCharacter({ name: "Kim" }), // Initialize with a character named Kim
      ...createCharacter({ name: "Sera" }), // Initialize with a character named Sera
    } as { [characterId: string]: Character },
    locationCharacterIndex: {
      base: new Set(["Kim", "Sera"]),
    } as { [locationId: string]: Set<string> },
  },
  actions: {},
    },
});```

My code currently works but there are typescript errors. When I change the code to `state.characters.characters[characterId];` it no longer works because characters is undefined.

Can you create a reproduction with typescript playground?

I spent a while trying to recreate it and couldn't. Then I deleted / reinstalled node_modules and deleted my previous store and everything seems to be working.

Not sure why migrating broke things but everything seems to be working now!
