Debounce Vuex Action Call to Database Not Working - vue.js

Question

I have a few components that can be separate or on the same page. Each of these components uses the same Vuex state. Since they can each be used on other pages and still work, each of them dispatches a call to the same Vuex action which in turns calls a service that uses axios to get the JSON data.
All of this works great!
However, when I do have 2 (or more) of these components on a single page, that axios call gets called 1 time for each of the components. Initially, I went down the path of trying to see if data existed and get created a "last got data at" timestamp so I could just bypass the 2nd call. However, these are happening both on the components created event and are being essentially called at the same time.
So, enter debounce. Seems like the exact reason for this. However, when I implement it, it fails and is passing on to the next line of code and not awaiting. What am I doing wrong?
Agenda Component (one that uses the same state)
async created() {
await this.gatherCalendarData();
},
methods: {
async gatherCalendarData() {
await this.$store.dispatch('time/dateSelected', this.$store.state.time.selectedDate);
},
},
Month Component (another, notice they are the same)
async created() {
await this.gatherCalendarData();
},
methods: {
async gatherCalendarData() {
await this.$store.dispatch('time/dateSelected', this.$store.state.time.selectedDate);
},
},
The Action getting called
async dateSelected(context, data) {
let result = await getCalendarData(isBetween.date, context.rootState.userId);
await context.commit('SET_MONTHLY_DATA', { result: result.Result, basedOn: isBetween.date });
},
This getCalendarData method is in a service file I created to make api calls (below.)
This is the error that I receive (once for each component) that calls this action.
[Vue warn]: Error in created hook (Promise/async): "TypeError: Cannot read property 'Result' of undefined"
Which is referring to the 3rd line above: result: result.Result
API Service
const getCalendarData = debounce(async (givenDate, userId) => {
let response = await getCalendarDataDebounced(givenDate, userId);
return response;
}, 100);
const getCalendarDataDebounced = async (givenDate, userId) => {
let result = await axiosGet('/api/v2/ProjectTime/BuildAndFillCalendarSQL', {
givenDate: givenDate,
userID: userId,
});
return result;
};
Axios Wrapper
const axiosGet = async (fullUrl, params) => {
let result = null;
try {
let response = await axios.get(fullUrl, params ? { params: params } : null);
result = await response.data;
} catch(error) {
console.error('error:', error);
}
return result;
};
If I put console.log messages before, after and inside the getCalendarData call as well as in the getCaledarDataDebounced methods: (assuming just 2 components on the page) the 2 before logs show up and then the 2 after logs appear. Next the error mentioned above for each of the 2 components, then a single 'inside the getCalendarData' is logged and finally the log from within the debounced version where it actually gets the data.
So it seems like the debouncing is working in that it is only run a single time. But it appears that await call let result = await getCalendarData(isBetween.date, context.rootState.userId); is not truly Waiting.
Am I missing something here?
EDITS after Answer
Based on #JakeHamTexas' answer, my action of dateSelected is now (actual full code, nothing removed like above as to not confuse anything):
async dateSelected(context, data) {
console.log('dateSelected action');
let isBetween = isDateWithinCurrentMonth(data, context.state);
if (!isBetween.result) {
// The date selected is in a different month, so grab that months data
return new Promise(resolve => {
getCalendarData(isBetween.date, context.rootState.userId)
.then(result => {
console.log('inside promise');
context.commit('SET_MONTHLY_DATA', { result: result.Result, basedOn: isBetween.date });
context.commit('SET_SELECTED_DATE', isBetween.date);
context.commit('statistics/TIME_ENTRIES_ALTERED', true, { root: true });
resolve();
});
});
} else {
// The date selected is within the given month, so simply select it
context.commit('SET_SELECTED_DATE', data);
}
context.commit('CLEAR_SELECTED_TIME_ENTRY_ID');
},
And my API call of getCalendarData is now:
const getCalendarData = async (givenDate, userId) => {
console.log('getting calendar data');
let result = await axiosGet('/api/v2/ProjectTime/BuildAndFillCalendarSQL', {
givenDate: givenDate,
userID: userId,
});
return result;
};
The error is gone! However, it does not seem to be debouncing - meaning everything gets called 3 times. I would expect the dateSelected action to be called 3 times. But I would like to avoid the getting calendar data being called 3 times. If it helps, this is what the console looks like:
dateSelected action
getting calendar data
dateSelected action
getting calendar data
dateSelected action
getting calendar data
inside promise
inside promise
inside promise

You need to return a promise from your action. Returning a promise of undefined (which is what is currently happening) resolves immediately.
dateSelected(context, data) {
return new Promise(resolve => {
getCalendarData(isBetween.date, context.rootState.userId)
.then(result => {
context.commit('SET_MONTHLY_DATA', { result: result.Result, basedOn: isBetween.date });
resolve();
}
}
},
Additionally, a vuex commit does not return a promise, so it doesn't make sense to await it.
