ebook-convert parameter recognition bug

[gitcoinkuang]

I filled in the following parameters in the Calibre eBook converter settings in Calibre-web：
--chapter "//*[re:test(., '^\s*第[零一二三四五六七八九十百千0-9]+(章|回).*', 'i')]"

txt to EPUB conversion error：
[2024-10-20 09:36:45,100] INFO {cps.editbooks:322} converting: book id: 7 from: TXT to: EPUB

[2024-10-20 09:37:17,916] DEBUG {cps.updater:331} Stable version: {'version': '0.6.23'}

But I can execute it in the terminal using the command：
ebook-convert "/books/未知/斗破苍穹 (7)/斗破苍穹 - 未知.txt" "/books/未知/斗破苍穹 (7)/斗破苍穹 - 未知.epub" --chapter "//*[re:test(., '^\s*第[零一二三四五六七八九十百千0-9]+(章|回).*', 'i')]" --language zh --chapter-mark both --page-breaks-before "/" --no-default-epub-cover

I want to know if it is a bug in the program or my problem

Looks like a bug

Please update to the newest nightly version, it should work now
