Error when parsing date

I'm getting an error when formatting a variable with datetime.
This is the template I wrote:

```md
---
template_title: {{datetime format = "dddd D [de] MMMM de YYYY"}}

---
#### {{datetime format="HH:mm:ss"}}:

---
```

I get the following error:

Here's my setup:

Joplin 3.5.13 (prod, win32)
Templates: 3.0.0
