Shopify page showing a Discount box error at console

[KidSmithy]

Hello, currently I am facing this error when I inspect my page website and look at the console, is it an important error? If so, can anyone help me fix it

Access to XMLHttpRequest at 'https://on.engines.app/discount-box/discount-box-front/public/index.php/api/discount-box ' from origin 'website link' has been blocked by CORS policy: No 'Access-Control-Allow-Origin' header is present on the requested resource. 

Thank you

Looking at the url this isn't to do with the Shopify platform itself but at a guess would be related to a discounting app (prob this one based on file name) you might be using. Best contact them about that but any blocked file would suggest something won't be working as you hoped.

If you're concerned, run through the customer journey and see if the path to checkout isn't broken. If you don't use the app anymore - remove it.
