getting promise instead of value in laravel vue js [duplicate] - vue.js

Question

I am calling an async function which loads the profile pic, the await call returns the value to the variable 'pf' as expected, but I couldn't return that from loadProfilePic. At least for the start I tried to return a static string to be displayed as [object Promise] in vue template.
But when I remove await/asnyc it returns the string though.
<div v-for="i in obj">
{{ loadProfilePic(i.id) }}
</div>
loadProfilePic: async function(id) {
var pf = await this.blockstack.lookupProfile(id)
return 'test data';
//return pf.image[0]['contentUrl']
},

That is because async function returns a native promise, so the loadProfilePic method actually returns a promise instead of a value. What you can do instead, is actually set an empty profile pic in obj, and then populate it in your loadProfilePic method. VueJS will automatically re-render when the obj.profilePic is updated.
<div v-for="i in obj">
{{ i.profilePic }}
</div>
loadProfilePic: async function(id) {
var pf = await this.blockstack.lookupProfile(id);
this.obj.filter(o => o.id).forEach(o => o.profilePic = pf);
}
See proof-of-concept below:
new Vue({
el: '#app',
data: {
obj: [{
id: 1,
profilePic: null
},
{
id: 2,
profilePic: null
},
{
id: 3,
profilePic: null
}]
},
methods: {
loadProfilePic: async function(id) {
var pf = await this.dummyFetch(id);
this.obj.filter(o => o.id === id).forEach(o => o.profilePic = pf.name);
},
dummyFetch: async function(id) {
return await fetch(`https://jsonplaceholder.typicode.com/users/${id}`).then(r => r.json());
}
},
mounted: function() {
this.obj.forEach(o => this.loadProfilePic(o.id));
}
});
