lunr search_within_pages regressed in v4.25.0 - Liquid syntax error: Expected end_of_string but found id in assets/js/lunr/lunr-store.js

[brackendawson]

What happened?

• Minimal Mistakes version: 4.25.0
• Ruby gem or remote theme version: remote theme
• Jekyll version: 3.9.3 (via githib-pages@228, it's also broken after updating to 3.9.5 via github-pages 231)
• Git repository URL: winchesterchess/winchesterchess.github.io@7f9eb8f (use this commit)
• Hosted on GitHub Pages (if yes provide URL to site): https://winchesterchess.uk/
• Operating system: macOS 12.7.4

Since the release of v4.25.0 my site no longer builds. I was not constraining the minimal-mistakes version in my _config.yml so I had picked up 4.25 automatically. I was getting the following locally:

Expected behavior

I expected the site to build, as it did before the 4.25.0 release.

Steps to reproduce the behavior

bundle exec jekyll serve

Other

Updating the github-pages gem to version 231 (latest) yields the same issue.

I found two changes which independanly fix this:

1. Rolling back to v4.24.0 by setting remote_theme : "mmistakes/minimal-mistakes@4.24.0" in the _config.yml
2. Setting lunr.search_within_pages to false.

So it looks relagted to some change in the lunr search but only when indexing pages. I tried to re-create this on a fresh install of minimal-mistakes on a blank jekyll site but search_within_pages works there, so probably something to do with my pages. I've tried deleting all my pages and layouts, but still no luck.

I think I've got it in 7ea8510. Can you try building your site with remote_theme: mmistakes/minimal-mistakes@7ea8510d4f554e670bfd2c3c30ed3a2fc3a39323 and see if it's fixed? My local clone from your given commit is now building without error.

[brackendawson]

Yes, fixed, thank you for the amazingly fast turnaround!

[iBug]

Fixed as of 4.25.1.
