Pro version: Preview Thumbnail not displaying?

[dfaltermier]

I just installed the Pro version of the Media Library with Laravel 11 (upgraded from v10). I am trying to get a single image upload form working using 'x-media-library-attachment'. I think I have it working, being able to drag-n-drop an image into the file upload form. However, when I save the form, the controller saves the file okay, and then redirects the user back to the same 'edit' page.

What I notice is that the thumbnail preview is not displayed on page reload. I guess I expected the preview of the saved image would be pre-loaded into the form and displayed so that the user can 'remove/delete' the image and/or upload a new image to replace it.

Question: Should I expect the thumbnail to be displayed? If so, am I missing something in my code?
Can anyone help? I'm stuck. Thanks.

Notes:

• The temporary upload file automatically uploads successfully and is recorded in the DB.
• The uploaded file is stored in the /public folder just fine and is accessible via a url.
• There are no Chrome debugger console errors.

Below are screenshots of my screen and code.
