How in methods function call variable from vuex store?

Question

In my Vue.js component, I have v-select element. When the user selects some value in that widget I call toDo function which is defined in methods block. As you can see in that function I want to know the value of the getter called filters . Unfortunately, it returns me undefined . At the same time in DevTools of Vue I notice that this getter has value. How in function correctly take the value of the getter?

QUESTION:

I use filters in the template and they are displayed on the interface without any problem. But in toDo function, the same filters return undefined result. I want to understand this strange behavior.

<div
    v-for="filter in filters"
    :key="filter.id">
    <v-checkbox
        v-for="(item, index) in filter.values"
        :label="filter.description_values[index]"
        :value="item"
        :key="item"
        v-model="filter.selected_values"
        hide-details>
    </v-checkbox>
    <v-select
        v-if="filter.widget==='single_dropdown'"
        v-model="filter.selected_values"
        :items="filter.filter_values"
        label="Select ..."
        dense
        solo
        @change="toDo">
    </v-select>
</div>

***
computed: {
  ...mapGetters('store', [
    'filters'
  ]),
},
methods: {
  toDo: async (value) {
    await console.log(this.filters) // result: undefined
  }
}

Vuex Storage :

import { api } from '../../services/api'

export default {
  namespaced: true,
  state: {
    filters: null
  },
  getters: {
    filters: state => state.filters
  },
  mutations: {
    setStateValue: (state, {key, value}) => {
       state[key] = value
    }
  },
  actions: {
    getFilters: async (context) => {
      await api.get('/api/filters').then((response) => {
        context.commit('setStateValue', {
          key: 'filters',
          value: response.data
        })
      })
    }
  }
}

Answer 1

In your mapGetters computed, call all getters inside a one Array:

computed: {
  ...mapGetters(['store', 'filters']),
},

Answer 2

The filters getter is at the root of your store; it's not inside a module. You can access it without namespacing:

computed: {
  ...mapGetters(['filters']),
},

Answer 3

At first - if Vuex code you provided is your main store (not a part of a module) you should remove namespaced: true, - it is used solely for vuex modules.

and if Vuex code you provided is not part of a Vuex module you should simply map getters this way:

computed: {
  ...mapGetters(['filters']),
},
