How to tell what the "Type" is of a content for display in recent-articles?

[rshmhrj]

My content folder has refs and posts, and in params.toml I added mainSections = ["posts", "refs"] and homepage.showRecent = true.

Some of the most recent articles aren't displaying.

I looked into recent-articles.html and changed this line:

{{ range first .Site.Params.homepage.recentLimit (.Paginate (where .Site.RegularPages "Type" "in" .Site.Params.mainSections) .Site.Params.homepage.recentLimit).Pages }}

to this:

{{ range first .Site.Params.homepage.recentLimit (.Paginate .Site.RegularPages .Site.Params.homepage.recentLimit).Pages }}

and the newer articles are displaying.

I can't tell what "Type" "in" .Site.Params.mainSections is doing, or how to update the frontmatter of those articles correctly (if necessary).

Any suggestions @jpanther or other Congo users?
