Address Validation Issue After Deploying Extension-only Shopify App

Hello,

I’ve recently begun learning Shopify app development and I’m currently working on a checkout extension for address validations. During development, everything works as expected—I can see my validations and errors without any issues. However, when I deploy the app using Yarn deploy, it gets deployed on my Shopify partner account. I generated the distribution link and installed it in one of my test stores. Unfortunately, when I input an address, I don’t see any error messages displayed. Instead, in my console, I’m encountering the error Failed to load resource: net::ERR_NAME_NOT_RESOLVED, which seems to be related to trying to connect with a Cloudflare URL.

I’ve followed the documentation closely, so I’m unsure why I’m encountering this error. Could you please advise on how to resolve it?

Thank you in advance.

Did you ever get it resolved? I’m having the same issue. I’ve been banging my head on it all day.
