When I call the function sites.fetch() in the google console this error appears Cross-Origin Read Blocking (CORB) blocked cross-origin response https://api.nutritionix.com/v1_1/search?callback=jQuery351004426279547866718_1648579753369&\_=1648579753370 with MIME type application/json. See https://www.chromestatus.com/feature/5629709824032768 for more details.i read about it and seems i need to add some headers but i don't know how to add on backbone.js.

Here my code:

App = {};

App.Site = Backbone.Model.extend();
App.Sites = Backbone.Collection.extend({
    url: "https://api.nutritionix.com/v1_1/search",
    model: App.Site,
    fetch: function(options){
        options = options || {};
        options.dataType = 'jsonp';
        Backbone.Collection.prototype.fetch.call(this, options);
    }
    
});

App.LoadSites = Backbone.View.extend({
    initialize: function(){
        this.listenTo(this.collection, 'add', this.renderOne);
        this.listenTo(this.collection, 'reset', this.renderAll);
        this.listenTo(this.collection, 'sync', this.renderAll);
    },

    tagName: 'ul',
    className: 'Sites',
    render: function(){
        this.collection.trigger('reset');
        return this;
    },

    renderAll: function(){
        this.$el.empty();
        this.collection.forEach(this.renderOne);
    },

    renderOne: function(site){
            loadSite = new LoadSite();
            loadSite.model = site;
            loadSite.render().$el.appendTo(loadSites.el);
    }

});


App.LoadSite = Backbone.View.extend({
    template: _.template('<p><strong><%= text %></strong></p>'),
    tagName: 'li',
    className: 'Site',

    render: function(){
        var innerHTML = this.template({text: this.model.get('text')});
        this.$el.html(innerHTML);
        return this;
    }

});


var loadSite, sites;

$(function() {
    
    sites = new App.Sites([]);

    loadSites = new App.LoadSites({
        collection: sites
    });

    loadSites.render().$el.appendTo('#back');
    console.log('veiw rend')
})

I tried other things but I couldn't solve it.
