"*** is corrupt or not an image" while openning cbz files in broswer

I coverted several zip format comics to cbz using calibre and uploaded it to calibre-web. Then got this error while trying to view in broswer. The books can be openned normally after downloading back so I assume the files were not actually corrupted.

Seems nothing wrong in log.
