Hello.

Script never finishes. I get this crash:

Any idea what and where to look to debug this?

I have manualy opened and saved all the problematic files and generation went on. They were images from a bathroom tile preview generator.

It would be helpful if you could share the image. Just in case it is not private.

Not private. Just layout of our bathroom from the shop. Here are few of them that caused that error. I have opened them in Paint.NET, saved and reuploaded.

So far no new issues and it slowly generates all previews:

Here is one file:

Not sure if github changes anything in uploaded images. But here are also few more zipped:

Great addon for Nextcloud by the way. Switched from Immich and Seafile to Nextcloud with Memories. Loving it so far, but scrolling down too far and server CPU went up to 100% fast. Hoping pregenerating images will help.

Thanks a lot! I was able to confirm that my fix solves your issue.
