nuxtServerInit无法正常工作（不更改状态）

Question

我当前的问题是我想初始化应用程序以将一些用户变量设置为状态，但是无法按预期运行，这是我当前的nuxtServerInit代码：

store / index.js

import { usersCollection } from '~/plugins/firebase.js'
const COOKIE_NAME = '__session'

export const state = () => ({
  locales: ['en', 'es', 'it'],
  locale: 'en'
})

export const mutations = {
  setLanguage(state, locale) {
    if (state.locales.indexOf(locale) !== -1) {
      state.locale = locale
    }
  }
}

export const getter = {
  getLanguages: state => state.locales,
  getLanguage: state => state.locale
}

// TODO
export const actions = {
  nuxtServerInit: (process.server && !process.static) ? async function({ commit, dispatch }, { req, store }) {
    if (!req.headers.cookie) { return }
    // CUSTOM 
    const admin = await import('firebase-admin');
    const key = require('../keys/service-account.json') // You will get it inside your firebase project settings

    // eslint-disable-next-line import/no-mutable-exports
    let adminApp

    if (admin.apps.length > 0) {
      adminApp = admin
    } else {
      adminApp = admin.initializeApp({
        credential: admin.credential.cert(key)
      })
    }
    // CUSTOM END

    //if (!admin.apps.length) {
    //  return;
    //}

    const cookie = await import('cookie');
    const parsedCookies = cookie.parse(req.headers.cookie);

    if (!parsedCookies) { return; }
    const idToken = parsedCookies[COOKIE_NAME];
    const JWTDecode = (await import('jwt-decode')).default;
    let decodedAuthUserClaims = null;
    try {
      decodedAuthUserClaims = JWTDecode(idToken);
    } catch { }

    if (decodedAuthUserClaims == null) { return; }

    try {
      const decodedToken = await adminApp.auth().verifyIdToken(idToken, true)
      const uid = decodedToken.uid
      if (uid) {
        console.log('UID: ', uid)
        commit('user/setUid', uid)
        dispatch('user/fetchUserProfile')
      }
    } catch {

    }
  } : () => { },

  setLanguage({commit, rootState}, locale) {
    commit('setLanguage', locale)
    // Adding preferred language
    usersCollection.doc(rootState.user.uid)
    .update({
      preferredLanguage: locale
    })
  }
}
