Cara menggunakan async nuxtserverinit di store

Saya telah mengikuti tutorial memindahkan data di vuex store, tetapi async nuxtServerInit tidak berfungsi, mohon di koreksi bila salah

ini file index.js di store

import axios from '~/plugins/axios'

export const state = () => ({
    customer:[]

})

export const mutations = {
    setCustomer(state, items){
        state.customer = items
    }
}

export const actions = {
    async nuxtServerInit( {commit} ){
        console.log("troololollo")
        const { data } = await axios.get('all_customer')
        commit('setCustomer',data.data)
    }
}

ini file index.vue

<script>
  import { mapState } from 'vuex'

  export default{
    computed: mapState([
      'customer'
    ])
  }

</script>
