Error on First-Time Access to Content Fragment UI

Hi everyone,

I have a issue when open content fragment as steps below,

When clicking on a Content Fragment in /aem/start.html, the application open a new tab, but an error is displayed initially. However, after refreshing the page, the Content Fragment data loads correctly.

Upon inspecting the browser console, a CORS (Cross-Origin Resource Sharing) error is observed. It's unclear why this issue is occurring specifically in the NON-PROD environment, as it doesn't appear in other environments.

Please let me know if you’ve encountered a similar issue or have any insights on how to resolve it.

hi @dante8888, this behavior is quite unusual. I recommend that you contact Adobe support immediately so they can investigate it thoroughly.
