Hugo new 'did not find expected node content' - what did it expect?

I am getting a message did not find expected node content from an archetype when I try to hugo new it.

Does anyone have any ideas what it wants from me?

The archetype reads:

title: aaa
date: {{- .Date -}}
draft: true

**Insert Lead paragraph here.**

Syntax looks okay. Not sure if it autocorrected when you typed your snippet, but is the front matter surrounded properly, with 3 hyphens?

key: value

@zwbetz, sorry, wrong formatting in the forum. It is three hyphens.

---
title: aaa
date: {{- .Date -}}
draft: true
---

**Insert Lead paragraph here.**

Edit: solved it, it was the date format. It should be {{ .Date }} of course.

How does that even work? Isn’t that circular?

It’s included in the default archetype
