No pic safe on Sent to comand

[Peter1980FFM]

I have Insert the Code

sendTo('cameras.0', 'image', {
    name: 'cam1', 
    width: 100, // optional 
    height: 50, // optional
    angle: 90   // optional
}, result => {
    const img = 'data:' + result.contentType + ';base64,' + result.data;
    console.log('Show image: ' + img);    
}); 

in the Javascript part in Blockly,
It will generate the Raw and wrote it in the Console but not generate a Picture to send
Could you please update this?
