The bug

Hi!
This happens when the preview has not yet been generated by the server after success upload.

I suggest a solution: replace this message with "the preview has not yet been generated, refresh the page" or implement an auto-refresh function after the preview is generated.

This message is misleading to users.
The image is actually uploaded, but the message is misleading.
