I just upgraded to Hugo 0.132.0 via Brew, and when I start the server I get the following error:

hugo v0.132.0+extended darwin/arm64 BuildDate=2024-08-12T15:21:36Z VendorInfo=brew

panic: runtime error: invalid memory address or nil pointer dereference

I added the new Blockquote render hooks config to my config.toml and copied the code in the documentation for layouts/_default/_markup/render-blockquote.html but this seems to be unrelated to those changes, because I get the same problem even after reverting back those files.

See Check blockquotes nilpointer · Issue #12756 · gohugoio/hugo · GitHub

This is very odd, as we have certainly tested this on many sites without similar issues … OK, I see it now, I guess you have an empty blockquote.

Oh, an empty blockquote in an existing post? That’ll be easy to track down… :wink:

Let me know if you want me to test something, I’ve only tested this locally on my MacBook and have not deployed to my live site on Netlify yet, naturally.

The issue was easy to locate and fix: Fix nilpointer regression with empty blockquotes by bep · Pull Request #12757 · gohugoio/hugo · GitHub

I will push a patch release later today.

Awesome, thanks @bep! I’ll test as soon as a new build is available in Brew. :slight_smile:

Saw 0.132.1 was available now, and I can confirm that it now works. My site renders properly locally again. Thanks for the quick turnaround @bep :slight_smile:
