Hey everyone, It looks like there was an update to the lunr extension that we use for the ref guide. This is an improvement that simplifies our build, but unfortunately it also broke the build.
I have a PR up that I will merge soon and backport to 9x and 9_0, just want to give everyone a heads up if they see the jenkins failures or have failures of their own locally or on github. Just pull from the latest main soon (after the merge) and it should work. https://github.com/apache/solr/pull/878 - Houston
