In which of these areas are you experiencing a problem?
Extension
Expected behavior
Preview of my customer-account-ui extension
Actual behavior
When I run shopify app dev command, the CLI starts my local development server to dev my app. I use the preview URL returned by the CLI to open the dev console on my shop back-office. From this Shopify dev console I click on the customer-account-ui preview link, but instead of rendering my extension, this preview link displays an infinite loader. There are no errors in the browser console or in the Shopify CLI terminal.
I am using the latest Shopify CLI version (3.92.1) and the bug appeared this morning. I didn’t have this bug a few days ago and my codebase + shopify CLI version are the sames.
I have already tested with different apps on different stores and the bug is always present
Reproduction steps
Start shopify app dev on app that used account-customer-ui extension
Open the preview link generated by dev console
@Valentin same thing hit us out of nowhere a while back with no code changes. A few things worth trying:
clear the CLI cache and restart:
shopify app dev --reset
if that doesn’t help, try opening the preview in a fresh incognito window — sometimes the dev console caches a broken state.
also worth checking if the issue is specific to customer-account-ui or if other extension previews load fine. if everything else works its likely something on shopify’s preview side for that extension type rather than your setup.
since you’re seeing it across multiple apps and stores it does sound like a platform side thing that started this morning, might be worth flagging to Shopify support with your CLI version so they can check if others are hitting the same thing.
I tried the shopify app dev --reset command and also to delete the .shopify folder generated by the CLI when launching the app dev command. Unfortunately, neither of these resolved the issue, the bug is still present.
I have already tried opening the preview link in private mode to ensure that the issue isn’t due to my cache or something similar.
Finally, I tried to generate a new fresh extension checkout-ui, and the preview link works fine for this type of extension.
As you said, I think there is a preview issue with the `customer-account-ui` extension type
I have had the same issue for the past three days. I tried shopify app dev on multiple computers. All three of my extensions: same thing: infinite loader. I have spoken to Shopify about this several times and am yet to receive a response. All development blocked. I tried creating a brand new extension and app: same thing. Shopify please update us on this. --reset doesn’t fix.
We’re still working on a fix for this, but it should only be affecting specific store plan types. DMing you to collect details to assist with troubleshooting.
