[BUG] Render of "page" failed

[KHannibal]

Describe the bug

When running the command hugo to build my websites, several errors appeared.

ERROR 2021/08/12 07:37:53 render of "page" failed: execute of template failed: template: posts/single.html:107:12: executing "content" at <partial "single/footer.html" .>: error calling partial: "/Sites/blog/themes/CodeIT/layouts/partials/single/footer.html:54:32": execute of template failed: template: partials/single/footer.html:54:32: executing "partials/single/footer.html" at <partialCached "function/path.html" $value $value>: error calling partialCached: partial that returns a value needs a non-zero argument.

What I did to fix the issue was to remove one $value in /layouts/_default/summary.html, at 69:32 in order to get
{{- $tag := partialCached "function/path.html" $value | printf "/tags/%v" | $.Site.GetPage -}} instead of
{{- $tag := partialCached "function/path.html" $value $value | printf "/tags/%v" | $.Site.GetPage -}}

I did the same in /layouts/partials/single/footer.html at 54:32.

Now my website builds properly.

Build Environment

• OS: macOS
• Theme version/commit : 0.2.0
• Hugo version : hugo v0.87.0+extended darwin/arm64

Additional Information

Could my fix be the cause of this issue #212 ?

Hi @KHannibal,

Can you send me the repository link to your blog?

[KHannibal]

Hi @victor-pogor,

You mean, you would like a copy of my website repository ?

[victor-pogor]

@KHannibal I just wanted to look in your blog repository to try to identify the root cause of this issue, but If your blog's source code is closed, it's ok, I'll try to find out without it. :)

[KHannibal]

No problem @victor-pogor, I will send you that by email. Some data such as ID and other sensitive materials will be removed, obviously. ;) Thanks in advance !

[KHannibal]

@victor-pogor repository sent. Thanks a lot !

Hi @KHannibal,

I was able to reproduce your issue. I analyzed your repository and the theme's code and I observed that the error persists when you have the tags with the empty content. So you have to remove all empty tags from your posts.

Scenario	Result
tags: [""]	❌
tags: []	✔️
tags: ["abc"]	✔️

Wow, I did not even notice that. Thanks a lot !!! 👍
And you killed two birds with one stone, since you simultaneously fixed the #212 issue. Let me know how I can offer you a coffee. :)
