I'm trying to load a graph timeline made by using vis.js, but i'm getting the error:

Traceback:
Error: No container provided
    at o.n._create (http://localhost:8069/web/content/500-8270a43/web.assets_backend.js:3316:153882)
    at new o (http://localhost:8069/web/content/500-8270a43/web.assets_backend.js:3316:99553)
    at http://localhost:8069/web/content/500-8270a43/web.assets_backend.js:3319:846

My js code:

odoo.define('test_timeline.timeline', function (require){    
    "use strict";
    var core = require('web.core');    
    var rpc = require('web.rpc');    
    var AbstractAction = require('web.AbstractAction');
    var QWeb = core.qweb;
    var TimelineDashboard = AbstractAction.extend({        
        start: function(){            
            var self = this;            
                rpc.query({                
                    model: 'project.project',                
                    method: 'get_project_record', //call python function                
                    args: [],}).then((res) => {
                         var container = document.getElementById('visualization');
                         //will use res on Dataset                
                         var items = new vis.DataSet([                  
                                {id: 1, content: 'item 1', start: '2013-04-20'},                  
                                {id: 2, content: 'item 2', start: '2013-04-14'},                  
                                {id: 3, content: 'item 3', start: '2013-04-18'},                  
                                {id: 4, content: 'item 4', start: '2013-04-16', end: '2013-05-19'},                  
                                {id: 5, content: 'item 5', start: '2013-04-25'},
                                {id: 6, content: 'item 6', start: '2013-06-27'},
                                {id: 7, content: 'item 7', start: '2013-05-27'},                  
                                {id: 8, content: 'item 8', start: '2013-05-27'},]);
                                // Configuration for the Timeline                
                                var options = {                  
                                        height: '500px'};// Create a Timeline              
                                var timeline = new vis.Timeline(container, items, options);                
                                self.$el.append(QWeb.render('TimelineDashboard', {}))            
})        }    })    core.action_registry.add('timeline', TimelineDashboard);
    return TimelineDashboard;});

My xml:

<?xml version="1.0" encoding="UTF-8"?>
<templates>    
<t t-name="TimelineDashboard">
    <div id="visualization"></div>
</t></templates>

I'm loading the vis lib through here:

<xpath expr="." position="inside">
