我正在学习 Angular11 中的状态管理。当我尝试制作减速器时出现错误。

类型参数 '(state: SharedState, action: { aspect_status: boolean; } & TypedAction<"[ side page ] side"> & { type: "[ side page ] aspect"; }) => { side: boolean; 微调器：布尔值；用户：用户；}' 不能分配给类型为 'OnReducer<SharedState, [ActionCreator<"[side page ] aspect", (props: { aspect_status: boolean; }) => { aspect_status: boolean; } & TypedAction<"[撇开页面]撇开">>]>'。

我试过这样

export interface SharedState {
  spinner: boolean;
  user: User;
  aside: false;
}
export const Initial_State: SharedState = {
  spinner: false,
  user: <User>{},
  aside: false,
};


export const loading = createAction(
  Loading_Action,
  props<{ spinner: boolean }>()
);

export const aside = createAction(
  Aside_Action,
  props<{ aside_status: boolean }>()
);

const _loading_reducer = createReducer(
  Initial_State,
  on(loading, (state, action) => {
    return {
      ...state,
      spinner: action.spinner,
    };
  }),
  // getting error here
  on(aside, (state, action) => {
    console.log(action);
    return {
      ...state,
      aside: action.aside_status,
    };
  })
);

微调器一正常工作，但抛开错误。

但是当返回类型是任何错误时，不会。我想知道为什么会这样。
