[1693] Problem: Vuex actions, dispatch from page

Hey, I've got problem with Vuex and fetch data. When i click to change route from menu it works but when i refresh page "f5" then it doesn't. But when I add console.logs I see that it works in terminal but I see that store is filled but I don't see it in browser. I do something like this

in index.vue
<script>
  export default {
    asyncData ({store}) {
      store.dispatch('GET_CATEGORIES')
    },
    computed: {
      categories () {
        return this.$store.state.categories
      },
      category () {
        return this.$route.params.category
      }
    }
  }
</script>

in store/index.js
export const state = () => ({  
  categories: []
})

export const mutations = { 
  SET_CATEGORIES (state, categories) {
    state.categories = categories
  }
}

export const actions = {
  async GET_CATEGORIES ({commit}) {
    const categories = await this.$axios.$get('http://icanhazip.com')
    commit('SET_CATEGORIES', categories)
  }
}
