Nil pointer dereference in /json/search-data.json with .File.BaseFileName after upgrading to v0.8.5

[nakednous]

Description

After upgrading from Hextra v0.8.4 to v0.8.5, the site build fails due to an error in /json/search-data.json. The .File.BaseFileName property references a nil value, leading to a runtime error. The issue occurs on a multilingual site with English and a partial Spanish translation.

Steps To Reproduce

1. Upgrade Hextra to v0.8.5.
2. Run hugo server --buildDrafts --disableFastRender.
3. Observe the error in the console.

Expected Behavior

The site should build successfully without errors.

Actual Behavior

The build fails with a nil pointer dereference error.

Hi, thanks for reporting. Do you have the link to the site source or a minimal reproducible example?

Caused by this https://github.com/imfing/hextra/commit/a97a1791cc518d9d78d7fc54deead77d65877895#diff-878d857f7dcdc7fd275c8ebd8d44c3894aee03519344b2cc1b55c079314a4bfeL10

The error is caused by a page that doesn't have a file, previously excluded because it didn't have Content either.

It could be fixed if pages without a File are excluded (??), but I'm also curious to see en example.

Right, that exclusion line is the only change we made. Not sure why page.File.BaseFileName would cause a nil pointer dereference panic, maybe could also be a Hugo bug?

@Gr3q i'll revert the search-data line change for now as I saw another person ran into the same issue

done, cut a new release that reverts the change in search-data.json: https://github.com/imfing/hextra/releases/tag/v0.8.6

will look into the root cause when I have time.
