how to fetch the frontmatter of any hugo markdown page (not just _index.md) - hugo

Question

I'm trying to write a shortcode for my hugo site that fetches the title parameter of page.
I have a directory structure like this:
content
├── workshops
│   ├── foo
│   │   └── _index.md
│   ├── bar.md
This works perfectly:
{{ with .Site.GetPage "home" "workshops/foo"}}
{{ .Params.Title }}
{{ end }}
And this one consistently comes up blank (even though there is a title in the markdown).
{{ with .Site.GetPage "home" "workshops/bar"}}
{{ .Params.Title }}
{{ end }}
My question is: How so I get the title of a standalone page?
I've tried a bunch of different combinations of things and I'm just not coming right. I've tried reading the docs and they are horribly convoluted on this point.

I have a solution! I wrote a little Python3.7 script to make directories and move and rename markdown files and just ran it over my entire contents directory. This solved my problem but is a bit of a hack...
import logging
import os
from pathlib import Path
def fixup(path):
location = Path(path)
assert location.is_dir(), location
for child in location.iterdir():
if child.is_dir():
fixup(child)
else:
fix_file(child)
def fix_file(file_path):
name = file_path.name
if not name.endswith(".md"):
# we only care about markdown files.
return
check_metadata(file_path)
if name.startswith("_index."):
# looks good
return
# make a directory with the same name as the file (without the extension)
suffix = ''.join(file_path.suffixes)
prefix = name[: -len(suffix)]
new_dir = file_path.parent / prefix
new_dir.mkdir()
new_path = new_dir / f"_index{suffix}"
file_path.rename(new_path)
def check_metadata(file_path):
""" given the path to a markdown file, make sure that the frontmatter includes
the required metadata
"""
# TODO
# required = ['title']
# allowed = ['pre', 'weight', 'ready']
if __name__ == '__main__':
fixup('content')

Two differences:
Use the global site variable
Just pass the page name as the argument
{{ with site.GetPage "workshops/bar" }}
{{ .Title }}
{{ end }}
