We refactored the TocTree adapter here #11565 (which also caused some other issues e.g., pydata/pydata-sphinx-theme#1404). However, TocTree is not meant to be a public API (there is no external documentation provided), so such internal changes should not considered as breaking changes (see pydata/pydata-sphinx-theme#1404 (comment) and pydata/pydata-sphinx-theme#1404 (comment)).

Now, in order to fix this, either pydata fixes it upstream or we could re-expose Toctree.get_toctree_ancestors as:

def get_toctree_ancestors(self, docname: str) -> set[str]:
    return _get_toctree_ancestors(self.env.toctree_includes, docname)

What do you think @AA-Turner

Had the same error with the docs stage in one of my (Gitlab) CI pipelines - I was leaving Sphinx unpinned, so it installed 7.2 in the runner. When I switched back to 7.1.2 the error went away. I thought this was a theme error so I posted in the pydata Sphinx theme project

pydata/pydata-sphinx-theme#1412

Please test with Sphinx 7.2.1.
