Build fails - related to Scratch in meta.html

[TheGroundZero]

Hi

I was attempting to to migrate my site from its current theme to this one but on build (using Github Actions) it fails.

I notice two different error messages:

• <.Scratch.Add>: error calling Add: runtime error: invalid memory address or nil pointer dereference (occurs twice)
• Scratch is nil; wrap it in if or with

Both related to layouts/partials/head/meta.html

Run peaceiris/actions-hugo@v3
  with:
    hugo-version: latest
    extended: true
[...]
Run hugo --gc --minify --environment staging

Got the same

I have managed to compile it by deleting the two lines

{{ .Scratch.Add "title" " - " }}
{{ .Scratch.Add "title" .LinkTitle }}

in meta.html (lines 17-18), but it is an ugly hack and I am unsure what really happens.
