[JobService] Unable to run job handler (thumbnailGeneration/generate-preview): Error: Processed image is too large for the WebP format about immich

Duplicated of #4017

This is different from the other issue because this isn't a limit sharp sets, but a limitation of the WebP format itself. You can change the preview format to JPEG, refresh thumbnails for this image and change it back. Or if there are more images like this, keep it set to JPEG.

This issue is caused by WebP's limitations, but the real problem is that the thumbnail generator doesn't restrict the max dimensions.
The image has an aspect ratio of 1:46, which would look odd even if the thumbnail were created successfully.
I suggest limiting the aspect ratio to 1:10 at most. If an image exceeds this, just crop and scale the center part.
A similar approach could work for #4033 , There are also techniques to solve issues when cropping with sharp.
