Magento module shows warning "Please do not initialize JS component in php. Do it in template"

I have a ViewModel class. I am getting a warning for my magento module "Please do not initialize JS component in php. Do it in template". Could someone help me out?

File: xxx/xxx/xx/xxx/xx/trackScript.phtml

<?php
/** @var xxx\xxxx\xxx\DataViewModel $helper */
?>

<script type="text/x-magento-init">
    {
        "*": {
            "trackScript": {
                "domain": "<?= $helper->getDomain(); ?>"
            }
        }
    }
</script>
