[SOLVED] Simple Lightbox Example in Quarto

Simple Lightbox Example in Quarto

I've created a minimal example to troubleshoot a problem encountered with the Lightbox extension to Quarto.

The current error is

GET: /lightbox.html
Error running filter _extensions/quarto-ext/lightbox/lightbox.lua:
_extensions/quarto-ext/lightbox/lightbox.lua:113: attempt to call a nil value (field 'is_format')
stack traceback:

(There is nothing listed after "stack traceback".)

I've tried to replicate the "Simple Lightbox Example" from https://github.com/quarto-ext/lightbox.

I get this error when I try to render...

the book's lightbox.qmd through VS Code (using quarto preview, and several variations)
the stand-alone not-in-the-book.qmd through VS Code (using quarto preview, and several variations)
the book's lightbox.qmd through RStudio (using the "Render button)
the stand-alone not-in-the-book.qmd through RStudio (using the "Render button)
