title: Using VueJS + FeathersJS + Feathers-Vuex, getting this error: Uncaught TypeError: vue__WEBPACK_IMPORTED_MODULE_0__.default is undefined
body: <p>Here is the error:</p>
  <pre><code>Uncaught TypeError: vue__WEBPACK_IMPORTED_MODULE_0__.default is undefined
      &lt;anonymous&gt; index.js:7
      js app.js:96
      __webpack_require__ app.js:397
      fn app.js:643

      O app.js:446
      &lt;anonymous&gt; app.js:1532
      &lt;anonymous&gt; app.js:1534
  
  and here is my index.js (from the documentation for feathers-vuex)
  // src/store/index.js
  import Vue from 'vue'
  import Vuex from 'vuex'
  import { FeathersVuex } from '../feathers-client'
  import auth from './store.auth'
  
  Vue.use(Vuex)
  Vue.use(FeathersVuex)
  
  const requireModule = require.context(
    // The path where the service modules live
    './services',
    // Whether to look in subfolders
    false,
    // Only include .js files (prevents duplicate imports`)
    /\.js$/
  )
  const servicePlugins = requireModule
    .keys()
    .map(modulePath =&gt; requireModule(modulePath).default)
  
  console.log('1: ', requireModule.keys())
  console.log('2: ', servicePlugins)
  
  export default new Vuex.Store({
    state: {},
    mutations: {},
    actions: {},
    plugins: [...servicePlugins, auth]
  })
  </code></pre>
  <p>Also, here is my main.js
  import Vue from 'vue'
  import VueCompositionApi from '@vue/composition-api'
  Vue.use(VueCompositionApi)</p>
  <pre><code>import App from './App.vue'
  import router from './router'
  import store from './store'
  
  import './assets/styles/base.css'
  import './assets/styles/chat.css'
  
  Vue.config.productionTip = false
  
  new Vue({
    router,
    store,
    render: h =&gt; h(App)
  }).$mount('#app')
  </code></pre>
  <p>It seems the problem is with @vue/composition-api but I've been digging for days and cannot find out how to resolve this issue.  I am trying to rebuild the feathers-vuex-chat from the FeathersJS site using the newest version of VueJS, FeathersJS and Feathers-Vuex.  Any help would be greatly appreciated!</p>
