I added page redirect in my UI but it does not support my staging server. this is my url

<a href="<?php echo url_for("@product_ebook?ean={$product->getEan()}") ?>">Get Ebook</a>

My symfony route

product_ebook:
  url: /products/getEbookAvailability
  param: { module: products, action: getEbook }

I got only URL without param and value.
