I'm trying to register a Vuex module without success. Here's my code:

stores/index.js:

import Vuex from 'vuex';
import resourcesModule from './resources';

import axios from '@/helpers/axiosInterceptor';

Vue.use(Vuex);


export default new Vuex.Store({
  modules: {
    resources: resourcesModule
  },
  state: {...}})

stores/resources/index.js

export default {
    state: {
        resources: []
    },
    actions: {
        fetchResources(store) {
            const request = axios.get('/api/musical_resources');
            request.then((res) => {
                store.commit('setResources', res.data);;
            }); 
            return request;
        }
    },
    mutations: {
        setResources(state, payload) {
            state.resources = payload;
        }
    },
    getters: {
        resources({resources}) {
            return resources;
        }
    }
};

I'm trying to dispatch the "fetchResources" action from another component and that gives me " [vuex] unknown action type: fetchResources"

When I inspect the store object, in _modules property there is only the "root" property, so I suspect maybe I'm missing something when registering the module.

When I console.log(resourcesModules); in stores/index.js file everything looks fine.

So, what's my problem? Thank you very much

EDIT:

Also tryied this in stores/index.js:

import Vue from 'vue';
import Vuex from 'vuex';

import axios from '@/helpers/axiosInterceptor';

Vue.use(Vuex);


export default new Vuex.Store({
  modules: {
    resources: {
      state() {
        return {
          resources: []
        }
      },
      actions: {
        fetchResources(store) {
          const request = axios.get('/api/musical_resources');
          request.then((res) => {
            store.commit('setResources', res.data);;
          });
          return request;
        }
      },
      mutations: {
        setResources(state, payload) {
          state.resources = payload;
        }
      },
      getters: {
        resources({ resources }) {
          return resources;
        }
      }
    }
  },
  state: {...}})

Without success
