The facial recognition job just queues person thumbnail generation. The thumbnail generation itself is the same as always and queued the same way [here](https://github.com/immich-app/immich/blob/cef84f6cedef1c7f83027327474681d92d685845/server/src/services/media.service.ts#L121) when clicking _All_ or _Missing_. All...

_All_ not regenerating the thumbnails is weird. A few things come to mind: 1. We don't handle the preview size being different from when the faces were detected (see #8317)....

That's fine! I'll see if I can reproduce this. If the person thumbnails do get regenerated under normal circumstances, then it means the jobs are failing in your case.

I tested and the person thumbnails really are queued and generated when running thumbnail generation on all assets. Setting the logging to verbose and running _All_ shows `Cropping face for...

> why is the server not regenerating them The jobs are most likely failing for the reasons [above](https://github.com/immich-app/immich/issues/8982#issuecomment-2068086160), which we're already aware of. Sharing the full verbose logs after running...

That should be fixed via #9126, but you're right that it hasn't made it into a release yet.

That's an interesting log. Encountering that error would prevent any ~~later~~ people from getting queued for thumbnail generation.

Using the `ghcr.io/immich-app/immich-server:pr-9195` image for `immich-microservices` and re-running *should* fix that issue. Would you be able to try it?

> Yes I'll try, thank you! Do I have to regenerate all thumbnails or only missing ones would do it? I think it'd have to be all thumbnails for the...

I tested and this isn't actually a bug. It's just that HEIC isn't a web-compatible format so we never load the original, whereas we do load the original on zoom...
