Summary of the issue you are facing:
Last week, previews stopped showing up for new photos taken on my iphone and uploaded to nextcloud. I am getting thousands of errors showing up in the log. This appears to be related to a problem with imagemagick which has been fixed in recent upgrades. Do we need to upgrade the imagemagick that ships with AIO?
ImageMagick version that ships with AIO currently is 7.1.1-32. Most recent version is 7.1.1-41.
root@2024-nextcloud-ubuntu-s-2vcpu-4gb-120gb-intel-nyc3-01:~# sudo docker exec --user www-data -it nextcloud-aio-nextcloud magick --version
Version: ImageMagick 7.1.1-32 Q16-HDRI x86_64 22207 https://imagemagick.org
Copyright: (C) 1999 ImageMagick Studio LLC
License: https://imagemagick.org/script/license.php
Features: Cipher DPC HDRI Modules OpenMP(4.5)
Delegates (built-in): bzlib cairo fftw fontconfig freetype gslib heic jng jpeg jxl lcms ltdl lzma pangocairo png ps raw rsvg tiff webp x xml zlib zstd
Compiler: gcc (13.2)
Steps to replicate it (hint: details matter!):
- Take some photos using iphone with iOS 18.1.1
- upload photos to nextcloud
- see that previews are not generated
- visit logs to see errors
Also, running magick from console generates the same error when processing a photo taken since I upgraded my iphone:
root@2024-nextcloud-ubuntu-s-2vcpu-4gb-120gb-intel-nyc3-01:~# sudo docker exec --user www-data -it nextcloud-aio-nextcloud magick identify -format "%m,%w,%h\n%[EXIF:*]" "/mnt/ncdata/nnn-1/files/nnn Photos/2024/12/24-12-03 08-50-07 7496.heic"

As compared to processing an older photo that works:

Tips for increasing the likelihood of a response
- Use the
preformatted textformatting option in the editor for all log entries and configuration output. - If screenshots are useful, feel free to include them.
- If possible, also include key error output in text form so it can be searched for.
- Try to edit log output only minimally (if at all) so that it can be ran through analyzers / formatters by those trying to help you.
