App embed extension blocks URL throwing 404

Shopify Apps

Expected behavior: When merchant adds app embed block, expected link to load app embed assets is throwing 404. This results into app embed block not loading.

Old URL: https://cdn.shopify.com/extensions/3415078e-1e03-44d0-a5eb-807108d6533a/1.3.0/assets/ef-faq-plus-script.min.js (Works)
New URL: https://cdn.shopify.com/extensions/3415078e-1e03-44d0-a5eb-807108d6533a/helplab-faq-page-product-faqs-0/assets/ef-faq-plus-script.min.js (throws 404)

Timeframe: This started happening yesterday (Feb 28th) evening. Other partners are also facing similar issues as per attached screenshot.

Environment: Production for multiple merchants.

Experiencing the exact same behaviour.

It really needs Shopify Dev’s attention. Frustrating to see this breaking our store.

Same issue is happening with us as well. On some stores the shopify CDN url has a different version number, which is leading to 404 errors.

We started seeing this as well. Identical behavior to what you describe.

I communicated this bug to Shopify on the 25th of February, I messaged them everywhere (facebook,slack, discord, github, twitter,email).

They still haven’t provide a solution, only yesterday did they recognized the issue through email.

You can check the github issue here where I explain in detail, the problem seems related to how Shopify is dealing with theme app extensions that have been uploaded before shopify cli version ~3.48:
https://github.com/Shopify/cli/issues/3488

How to fix it:

The way to fix it is just to deploy the exact same code you used in theme app extension but using any version after 3.48.0,

I personally use “@shopify/app”: “3.49.7”, because it doesn’t force you to start a graphiql server.

After you deploy the code, Shopify will serve the right link for your app (the CDN link will include “your-app-name-1” instead of “your-app-name-0”).

If you don’t have the last version that you deployed of your code, you’ll need to wait for them to provide a solution, I gave up after 24 hours because the last bug that I reported was around a year ago and they never even said anything about it.

Shopify responded back with message saying that they’ve identified and fixed this issue on their end so there won’t be any manual fixes needed on partner or merchants end.
