WebUI conversion failed for all comic cbz/cbr format, GUI works fine

[gotbletu]

Name : calibre
Version : 4.0.0-1
Architecture : x86_64
Kernel: 5.3.4-arch1-1-ARCH x86_64
Desktop: Xfce 4.14.1
Distro: EndeavourOS (Linux)

The GUI works fine with all cbr/cbz conversion.

This issue is only for the WEBUI (calibre-server)
Conversion does not work on any cbz/cbr to xxx format
e.g: Not Working
- cbz/cbr to epub [failed]
- cbz/cbr to mobi [failed]
...etc

e.g other format WORKS
- epub/txt to mobi [works]
- txt to epub [works]

so seems like its only an issue with cbr/cbz formats on WEBUI.

command used to run server:
$ calibre-server --port 57770 --userdb /srv/calibre/users.sqlite --enable-auth

Heres failed log message after hitting the Convert Button

I have not bug with tis config

1. go to "preference"
2. "input option"
3. check "Disable trimming" in "comic input"
