theme: guard access to page.File.Filename

[retorquere]

I'm trying to build my site, but as of just now I'm getting

"/Users/emile/github/better-bibtex/site/themes/relearn/layouts/_default/list.html:8:5": execute of template failed: template: _default/list.html:8:5: executing "menu" at <.Render>: error calling Render: "/Users/emile/github/better-bibtex/site/content/citing/_index.md:1:1": failed to execute template _default/views/menu.html: "/Users/emile/github/better-bibtex/site/themes/relearn/layouts/_default/views/menu.html:1:4": execute of template failed: template: _default/views/menu.html:1:4: executing "_default/views/menu.html" at <partial "menu.html" .>: error calling partial: "/Users/emile/github/better-bibtex/site/themes/relearn/layouts/partials/menu.html:32:16": execute of template failed: template: partials/menu.html:32:16: executing "partials/menu.html" at <partial "partials/inline/menu-tree" (dict "currentnode" $currentNode "config" $config "showvisitedlinks" $showvisitedlinks)>: error calling partial: execute of template failed: template: partials/menu.html:271:12: executing "partials/inline/menu-tree" at <partialCached "partials/inline/menu-walker" (dict "menu" .

I have an idea about what's going on here. Do you create pages that are not backed by a file?

[retorquere]

It's all just files on disk, do you mean pages could load things over the network during the build or some such? That's not in play here.

[McShelby]

What Hugo version are you using and could you share your repo?

[retorquere]

Ah upgrading from v0.141 -> v0.142 solved the problem.

[McShelby]

Would still be possible to take a look into your repo? As the theme claims to be compatible down to Hugo 0.126.0, I want to make sure that this is still the case.

[retorquere]

Absolutely -- really appreciate the follow-up! My repo is https://github.com/retorquere/zotero-better-bibtex/ but its setup is a little arcane; I have zipped up the pre-hugo-run state of the relevant part of the repo and uploaded it to https://limewire.com/d/7ee5344e-6885-406a-9e33-d2b9f219c2be#zB6wVOr3zcWBteQvW1djow6ddoJchlXYnlE5R6rPszM

0.142 works most of the time; I do still get the error sometimes, which is a little strange, as it does so under what I had assumed to be stable circumstances on github actions.

Thanks for reporting. I've pushed a fix to the themes main branch.
