Unable to find Tensor data while using Tensorflow.js's tf.browser.fromPixels()

    function trial(ss) {                            // ss is the image in base64 string
    let image = new Image();
    image.src = ss;
    image.onload = () => {
        let tensor = tf.browser.fromPixels(image, 3);
        Promise.resolve(tensor).then(r => {
            console.log(tensor);
            dispatch(initializeImageTensor({tensor}));
        });
    }
}

When i call trial i pass it a image in base64 form which is then passed to Image(). But when i check the output of tensor i am unable to find the actual array of data:

Where is the actual array/tensor data stored and do i use normal axios.post("URL", qs.stringify({tensor})) to send it to my backend. I'm using @tensorflow/tfjs not tfjs-node
