handlebar partial not working?

[davids701124]

I have my components build and display correctly already. Now I'm trying to take those components for prototyping. I followed the doc but I keep getting the error saying Error (fabricator-assemble): The partial could not be found. Could someone help? I provide a screenshot showing how I structure my UI components.

And here is my code:

---
title: My Custom Layout
---

<h1>Hello, World!</h1>
{{> 05-toggle-button}}

The number is not needed, and thus it should be {{ toggle-button }}.
