我在选项API中定义了这个存储：

import { defineStore } from "pinia";
import AxiosBeerOffice from "@/services/axiosBeerOffice";

const uri = {
  getNavbarItems: "/navbarItems",
};

export const useNavbarStore = defineStore({
  id: "navbar",
  state: () => ({
    navbarItems: [],
  }),
  actions: {
    getNavbarItems: async () => {
      const response = await AxiosBeerOffice.get(uri.getNavbarItems, true);
      const { data } = response;
      this.navbarItems = data;
    },
  },
});

问题是，当我调用getNavbarItems操作时，将值设置为navbarItems的行向我抛出以下错误：

我真的不明白发生了什么事，所以任何帮助将不胜感激。
