bug: drafts throw errors

[davidsneighbour]

Lately --- this is not pinnable to a version number, it just stopped working, after August 12th --- I am unable to use hugo server -D due to type casting errors:

Error: error building site: render: failed to render pages: render of "home" failed: "/home/patrick/github.com/davidsneighbour/kollitsch.dev/layouts/index.html:27:22": execute of template failed: template: index.html:27:22: executing "main" at <partials.Include>: error calling Include: "/home/patrick/github.com/davidsneighbour/kollitsch.dev/layouts/partials/content/post.html:5:31": execute of template failed: template: partials/content/post.html:5:31: executing "partials/content/post.html" at <partials.IncludeCached>: error calling IncludeCached: "/home/patrick/.cache/hugo_cache/modules/filecache/modules/pkg/mod/github.com/davidsneighbour/hugo-modules/modules/[email protected]/layouts/partials/func/getArticleClasses.html:2:23": execute of template failed: template: partials/func/getArticleClasses.html:2:23: executing "partials/func/getArticleClasses.html" at <.IsHome>: nil pointer evaluating interface {}.IsHome

The template in question is this:

{{- $classes := collections.Slice -}}
{{- if compare.Eq true .IsHome -}}{{/* <-- the error points here */}}
  {{- $classes = $classes | collections.Append "is-home" -}}
{{- end -}}
{{- if compare.Eq true .IsNode -}}
  {{- $classes = $classes | collections.Append "is-node" -}}
{{- end -}}
{{- if compare.Eq true .IsPage -}}
  {{- $classes = $classes | collections.Append "is-page" -}}
{{- end -}}
{{- if compare.Eq true .IsSection -}}
  {{- $classes = $classes | collections.Append (fmt.Printf "section section-%s" .Section ) -}}
{{- end -}}
{{- $classes = $classes | collections.Append (fmt.Printf "kind-%s" .Kind) -}}
{{- $classes = $classes | collections.Append (fmt.Printf "type-%s" .Type) -}}
{{- if compare.Eq true .Draft -}}
  {{- $classes = $classes | collections.Append "draft" -}}
{{- end -}}
{{- $classes = collections.Delimit $classes " " -}}
{{- return $classes -}}

and it worked before, I am pretty sure.

The only thing that changed is the version of Golang in my system (installed via Snap).

Could it be that something changed with the way Hugo works with typecasting? I can change the template by wrapping it with {{ with . }}, but then another template error takes over, this time complaining about another undefined value.

I tried to minimize the frontmatter of the draft post, to no change. As soon as I have any post with draft: true in it's frontmatter hugo server -D gives up.

Basically trying to use drafts results in my install having issues with undefined values that did not exist before.
