Ember.Computed is not a function - ember.js

Question

I'm trying to setup simple application with Ember using ember-chart:
https://www.npmjs.com/package/ember-cli-chart
I have my charts.hbs file:
<div class="container-fluid">
<div class="row">
<div class="col-md-12">
{{#toggle-section}}
<div class="chart-container">
{{ember-chart type=CHARTTYPE data=CHARTDATA options=CHARTOPTIONS width=CHARTWIDTH height=CHARTHEIGHT}}
</div>
{{/toggle-section}}
</div>
</div>
</div>
and my charts.js controller with sample from documentation of Chart.js:
import Controller from '#ember/controller';
import Ember from "ember";
export default Controller.extend({
CHARTTYPE: 'bar',
CHARTDATA: Ember.Computed('', function () {
return {
labels: ["Red", "Blue", "Yellow", "Green", "Purple", "Orange"],
datasets: [{
label: '# of Votes',
data: [12, 19, 3, 5, 2, 3],
backgroundColor: [
'rgba(255, 99, 132, 0.2)',
'rgba(54, 162, 235, 0.2)',
'rgba(255, 206, 86, 0.2)',
'rgba(75, 192, 192, 0.2)',
'rgba(153, 102, 255, 0.2)',
'rgba(255, 159, 64, 0.2)'
],
borderColor: [
'rgba(255,99,132,1)',
'rgba(54, 162, 235, 1)',
'rgba(255, 206, 86, 1)',
'rgba(75, 192, 192, 1)',
'rgba(153, 102, 255, 1)',
'rgba(255, 159, 64, 1)'
],
borderWidth: 1
}]
}
}),
CHARTOPTIONS: Ember.Computed('', function () {
return {
scales: {
yAxes: [{
ticks: {
beginAtZero:true
}
}]
}
}
}),
CHARTWIDTH: 500,
CHARTHEIGHT: 500,
});
In index.js route i have redirection to charts route:
beforeModel() {
this.replaceWith('charts');
}
When I am trying to open my localhost:4200 after ember s it gives me an error in console:
router.js:927 Error while processing route: index Ember.Computed is not a function TypeError: Ember.Computed is not a function
I tried to search for an answer but nothing seems to work.

The function is lowercase: Ember.computed
It would also be better to use this import:
import { computed } from '#ember/object';
to avoid having to bring in all of the Ember framework just to access the computed function.
