I'm in Vue 3, I started with adding a new Vuex.Store to vue, but I continuously get this javascript error. I also tried the same thing with createStore since I use Vue 3, but it's still the same.

What am I missing?

const store = new Vuex.Store({

    modules: {

    account: {

    namespaced: true,

    state: () => ({  }), 

    getters: {

        isAdmin () {  } 

    },

    actions: {

        login () {  } 

    },

    mutations: {

        login () {  } 

    }

 }}

});  

Than I add to Vue as store:

new Vue({

    router,

    store,

    render: h => h(App),

}).$mount('#app');

What am I missing?
