TypeError: 'WindowsPath' object is not iterable in ".convert_file()" method. Windows 10 x64

Hello. Sorry my bad english.

I install pypandoc by pip, i used the command:

pip install pypandoc_binary

But when i run simple script to convert file, this throws an exception. Script example:

import pypandoc
pypandoc.convert_file(os.path.abspath('00_01_start.txt'), to='markdown', format='dokuwiki', outputfile='00_01_start.md')

Exception in REPL:

Traceback (most recent call last):
  File "D:\my\projects\howdo_faq\[source]\wiki.qsp.org.mw\convert.py", line 18, in <module>
    main()

    output = pypandoc.convert_file(os.path.abspath('00_01_start.txt'), to='markdown', format='dokuwiki', outputfile='00_01_start.md')

RuntimeError: source_file is not a valid path

Input File is exist. Path to input file is string.

I use:

Windows 10 Pro x64 22H2
Python: 3.12.5
Pypandoc: 2.19.2

If i use ".convert_text()" method, the exceptions do not appear.

What do I wrong?

I look at the pypandoc's __init__.py. Method '_convert_input()'. Change line 383 by this line:

            input_file = [str(source)]

and script is work. But I don't know, where source parameter transform in WindowsPath, and and how will this affect the rest of the code.
