Not able to bind data in posts.hbs - ember.js

Question

templates/posts.hbs
<h2>Posts</h2>
{{#each model as |post|}}
<div>
<h3>{{post.postid}}</h3>
<h3>{{post.title}}</h3>
<h3>{{post.userid}}</h3>
<h4>{{post.description}}</h4>
</div>
{{/each}}
{{outlet}}
serializers/posts.js
import DS from 'ember-data';
export default DS.JSONAPISerializer.extend({
normalizeResponse(store, primaryModelClass, payload, id, requestType){
payload = {data: payload};
console.log(payload); //in console getting data here properly
return this._super(store, primaryModelClass, payload, id, requestType);
}
});
routes/posts.js
import Ember from 'ember';
export default Ember.Route.extend({
model(){
let posts = this.store.findAll('post');
console.log(posts);
return posts;
}
});
Getting data from backend API point and printing data in console properly. Everything fine.
But not binding in handlebars (posts.hbs). Can someone help me with this? New to ember Js.
In routes/posts.js from console.log(posts) I'm getting one error
reason: EmberError
