Convert not including subfolder when converting md to html

I'm trying to convert a directory containing .md files to an html site structure using obsidianhtml convert. The .md directory contains a subdirectory, containing an image that's referenced in one of the .md files. Here's a little example of the file structure:

.
├── md
│   ├── experiment-2-theory.md
│   ├── figures
│   │   └── unnamed-chunk-1-1.png
│   ├── homepage.md
│   ├── measurement.md
│   └── stimuli.md
├── rmd
│   ├── bayes-play.Rmd
│   ├── experiment2-theory.Rmd
│   └── stan-file.stan
├── tmp.txt
└── to_html
    ├── compile.sh
    ├── config.yaml
    ├── links.txt
    └── output

./md/experiment-2-theory.md references ./md/figures/unnamed-chunk-1-1.png.

Inside ./to_html, I'm running the command obsidianhtml convert -i config.yaml, and the contents of config.yaml are:

# The first folder that contains all obsidian files
# Use full path or relative path, but don't use ~/
obsidian_folder_path_str: '/home/dave/Dropbox (Lehigh University)/post_doc/professional/projects/gaita/ideation/structured/md/' 

# The note that will be used as the index.html 
# should be in obsidian_folder_path_str
# Use full path or relative path, but don't use ~/
obsidian_entrypoint_path_str: '/home/dave/Dropbox (Lehigh University)/post_doc/professional/projects/gaita/ideation/structured/md/homepage.md'

html_url_prefix: '/gaita/ideation/structured/html/'

toggles:
  process_all: True

The output of running the obsidianhtml convert -i config.yaml command is as follows:

> COPYING VAULT /home/dave/Dropbox (Lehigh University)/post_doc/professional/projects/gaita/ideation/structured/md TO /tmp/tmpaqunt9l5

    < COMPILING INDEX FROM DIR STRUCTURE: Done
    > SECOND PASS HTML
    < SECOND PASS HTML: Done

You can find your output at:
    md: /home/dave/Dropbox (Lehigh University)/post_doc/professional/projects/gaita/ideation/structured/to_html/output/md
    html: /home/dave/Dropbox (Lehigh University)/post_doc/professional/projects/gaita/ideation/structured/to_html/output/html

If I'm interpreting the backend correctly here, it looks like the rsync copy to /tmp may not be copying the ./md/figures/ directory causing this error when trying to convert to html: File figures/unamed-chunk-1-1.png not located, so not copied. @ /tmp/tmpaqunt9l5/experiment-2-theory.md ?

This is a really puzzling issue because this feature is working in this app in another Obsidian vault on my computer, and I could swear it was working earlier today and I'm not sure what would have changed.

Anything else I can provide to help you diagnose the issue?
