I cannot make this j - Githubissues

I cannot make work the animation. I can see the 3D model but no the animation. What am I doing wrong? This is the index.html code:

<body style='margin : 0px; overflow: hidden;'>

    <a-scene embedded arjs='sourceType: webcam; debugUIEnabled: false; detectionMode: mono_and_matrix; patternRatio: 0.9;'>

    <a-marker type='pattern' url='assets/pattern-marker.patt'
    smooth="true"
    smoothCount="10"
    smoothTolerance=".01"
    smoothThreshold="50">
        <a-entity
            gltf-model="assets/elgc.gltf"
            scale="10 10 10"
            rotation="0 -90 90"
            position="-0.8 0 0.3"
            animation-mixer="clip: idle; loop: repeat"
            >
        </a-entity>
    </a-marker>

    <a-entity camera></a-entity>
    </a-scene>
</body>
