Timeline Exception

CesiumJS
1

Hi community !, I'm having some troubles with the timeline, when I start the viewer with the timeline on,

var viewer = new Cesium.Viewer('cesiumContainer',
                                   {
        animation: true,
        timeline: true,
        sceneMode: Cesium.SceneMode.SCENE3D,
        homeButton: false,
        navigationHelpButton: false,
        baseLayerPicker: false,
    });

Cesium is giving me the next Banner.

An error occurred while rendering. Rendering has stopped.
TypeError: Cannot read property 'update' of undefined

    at t (http://localhost/js/lib/Cesium-1.13/Build/Cesium/Cesium.js:464:10458)

and in the Chrome console

message: "Invalid ISO 8601 date."

__proto__: t

But when animation is set to false this exception doesn't appear, the most rare is that the code was working sometime correctly with this option on.

Any Ideas if I need to set some date to the clock before the viewer ? I'm missing something here ?? ..

Thanks in Advance and let me know if I can help you to help me.

Hello,

I’m not sure what would be causing this problem. Can you try using the unminified version of Cesium instead? That would give more useful error messages.

Best,

Hannah

Hi Hannah !

When I explained the detail of the problem I mistake in a word, when I wrote "But when animation is set to false this exception doesn't appear" it must be "But when TIMELINE is set to false this exception doesn't appear"

Well, to tell you something rare ? today the timeline is working again, so... trying to replicate the problem of the past week, First I back in time the clock of my machine to yesterday (Nov 10th) and it continues working ok, so I back in time the clock to November 8th and ... the error appears again!!, I simply don't understand why .....

I change the Cesium to de Unminified version Hannah. This is the output

An error occurred while rendering. Rendering has stopped.

Please, help me to understand why it's happening to avoid this situation or to fix this .

Thanks Again for your time and your concern.
