Extension

Expected behavior

I think the value of the metafield I defined should be returned

Actual behavior

I got an error. Uncaught (in promise) DOMException: Failed to execute 'importScripts' on 'WorkerGlobalScope': The script at 'https://additions-sharing-dry-contributor.trycloudflare.com/extensions/4cd1e515-5b02-4afd-b463-f94bbf4dc2c5/assets/checkout-ui.js' failed to load. at F (https://extensions.shopifycdn.com/shopifycloud/checkout-web/assets/ExtensionSandbox.latest.en.9b5ee1ea3fb85742fd63.worker.js:1:129387) at MessagePort.p (https://extensions.shopifycdn.com/shopifycloud/checkout-web/assets/ExtensionSandbox.latest.en.9b5ee1ea3fb85742fd63.worker.js:1:119473)

Verbose output

I created a new application and followed the step-by-step documentation below
https://shopify.dev/docs/apps/build/checkout/display-custom-data?extension=react
Then I got an error.
Uncaught (in promise) DOMException: Failed to execute 'importScripts' on 'WorkerGlobalScope': The script at 'https://additions-sharing-dry-contributor.trycloudflare.com/extensions/4cd1e515-5b02-4afd-b463-f94bbf4dc2c5/assets/checkout-ui.js' failed to load.

I made sure I didn't do any extra steps, then the store I chose was the developer store

Hi! Thanks for creating the issue and sorry for the late response.

We are not able to reproduce it, have you encountered this issue again? There was a Cloudflare outage on May 30 that may be related.
