I'm trying to get the value from the Vuex module state inside the mutation. But I'm always getting the Observer object instead of a real object.

@Module({
    namespaced: true,
    name: 'myModule',
    dynamic: true,
    store
})

export class MyModule extends VuexModule {
    public users: ArrayToObjMap<Users> = {};

    @Action
    public async initialize() {
      const fetchedUsers = await UsersService.getUsers();
      this.context.commit('setUsers', fetchedUsers);
    }

    @Mutation
    public setUsers(usersList: string[]) {
      this.users = GlobalUtils.mapIdsToItems(usersList, this.users)[0];
    }
}

Inside setUsers Mutation, the value of this.users is always Observer. I need to get the simple object to iterate through. I've already tried several solutions:

1. JSON.parse(JSON.strinfigy(this.users)); => returns empty object
2. cloneDeep(this.users); => returns empty object
