async/await actions in Vuex - vue.js

Question

I am wondering how to use async/await actions in Vuex. The docs provide this syntax as an example:
actions: {
async actionA ({ commit }) {
commit('gotData', await getData())
},
async actionB ({ dispatch, commit }) {
await dispatch('actionA') // wait for `actionA` to finish
commit('gotOtherData', await getOtherData())
}
}
Following this example, I have:
import Vue from 'vue';
import Vuex from 'vuex';
import * as firebase from 'firebase';
Vue.use(Vuex);
export const store = new Vuex.Store({
state: {
// other state vars here
resource: null
},
mutations: {
// saveValues
setResource(state, payload) {
state.resource = payload;
}
},
actions: {
async getResource({ commit, dispatch }) {
var resource
console.log('resource1: ' + resource)
Vue.http.get('https://mysite/api/getResource')
.then((response) => {
console.log('get resource')
var data = response.body;
resource = data.access_resource;
console.log('resource2: '+ resource)
commit('setResource', resource);
var foo = store.getters.resource;
console.log('resource3: ' + foo);
}, (error) => {
console.log(error);
});
},
async getSomeApi({ commit, dispatch }) {
console.log('getting api');
await dispatch('getResource');
var resource = store.getters.resource;
console.log('resource4: ' + resource);
Vue.http.get('https://somesite/api/someapi?resource=' + resource)
.then((response) => {
console.log("got something from somesite")
var data = response.body;
// do something with data -> payload
dispatch('saveValues', payload);
}, (error) => {
console.log(error);
});
}
},
getters: {
resource(state) {
return state.resource;
}
}
});
However, even following the syntax example found in the docs, when I run this code, the async/await seem to be completely ignored. When I look at the logs, I see, in the following order:
getting api
resource1: undefined
resource4: null
get resource
resource2: <expected-value>
resource3: <expected-value>
I expect the console.log statements to print out in numerical order. I would appreciate if someone could clarify what I am doing wrong.

You're not awaiting the Vue.http.get() promise in the getResource() method, so await dispatch('getResource') will resolve before the HTTP request has resolved.
Trimmed down:
async getResource() {
let response
try {
response = await Vue.http.get('https://mysite/api/getResource')
} catch (ex) {
// Handle error
return
}
// Handle success
const data = response.body
}
