mainSections not working

[krystalcode]

I have a fresh installation of PaperMod and content under content/posts does not display in the home page. The culprit line is the following, when I remove it things work. By the way, when I print the variable site.Params.mainSections it does seem to contain the correct value.

{{- $pages = where site.RegularPages "Type" "in" site.Params.mainSections }}

I have added the following to hugo.toml, following the example site.

mainSections = ['posts']

And also tried the following, according to this Wiki page.

[params]
mainSections = ['posts']

This Wiki page refers to the official mainSections method, but usage seems to be different. Tried the syntax suggested there but it does not work either.

• https://gohugo.io/functions/collections/where/#mainsections
• https://gohugo.io/methods/site/mainsections/

What am I doing wrong, and how can I troubleshoot this? Also, I think the inconsistency between the example site, the Wiki page and the official Hugo documentation of mainSections should be reconciled/clarified.

I traced this to a post named Index.org, apparently that's not supported/allowed? When I deleted that file things worked. Fairly new to Hugo. I think that mainSections in the example site should be corrected, and the relationship to Hugo's official mainSections method should be clarified.
