Search broken due to JavaScript "undefined"

[vsalvino]

At some point, the search has been broken (the built-in search, not algolia from the wagtail docs).

It is injecting "undefined" into the URLs when jumping to a specific page.

I'll investigate later whether this is due to a sphinx change or a JS change in our theme.

Example: https://docs.coderedcorp.com/wagtail-crx/index.html

• Search for "Contributing", select the suggested "Contributing" page (click or press enter).

• The page 404s. The URL contains an "undefined" which is causing the breakage.

  # Search URL
  https://docs.coderedcorp.com/wagtail-crx/undefinedcontributing/index.html
  
  # Real URL
  https://docs.coderedcorp.com/wagtail-crx/contributing/index.html

It does not seem to happen on the deployed version here https://sphinx-wagtail-theme.readthedocs.io/

@vsalvino were you able to resolve this? I am facing the same issue,

The deployed version was not using the latest version. It seems to have been recently deployed and now is exhibiting the issue.

Did a bit more digging... turns out this broke due to a change in Sphinx 7.2. I'm still tracing down the fix, but as a workaround, build with sphinx<7.2
