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

[AleksVersus]

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.

I've also the same error and this is working. Thanks!!

Out of the blue - this has become an issue for me too! I have no idea why.

I'm on Windows 11

[SudoCerb]

Seems to be an edge case - I will investigate further

[JessicaTegner]

@AleksVersus or @SudoCerb I'm happy for a pr fixing this.

[SudoCerb]

Will try isolate the issue this week and at least give some feedback.

Hi @JessicaTegner - in my instance it would appear that any file path that contains square brackets ([ or ]) would throw this error. I haven't yet stepped into pypandoc code to test yet

I am seeing the exact same issue. My file also has "[" and "]" in its name.

This is how to reproduce this bug - MacOS in my case:

import pypandoc
local_path: str = '/Users/foo/[Draft]mydoc.doc'
html_text = pypandoc.convert_file(local_path, "html", format="docx", sort_files=False, extra_args=[ '--extract-media=/tmp'])

The buggy line: args += input_file

The exception: TypeError: 'PosixPath' object is not iterable

If you pass sort_files=True you will hit the bug in the subject.

Overall the code seems to want to convert a str path to Path, but later on tests again, etc - overall it gets confused and has these failure points.

Bottom line:

• Path is not sortable, so you need to pass sort_files=False
• [ and ] in the name mean that str(source) will also cause issues.
