Transferring to ansys-sphinx-theme..? If not, we can move it back. Can you confirm whether the local build works?

[Andy-Grigg]

Just tried this locally, and it also fails, so I think this is a theme issue as opposed to a CI issue:

Same issue in https://github.com/ansys/pydpf-core/actions/runs/11819743733/job/32930389290?pr=1846

[jorgepiloto]

I am suspicious about something going on within this function:

ansys-sphinx-theme/src/ansys_sphinx_theme/search/fuse_search.py

Lines 191 to 229 in e91ee99

	def create_search_index(app, exception):
	"""
	Generate search index at the end of the Sphinx build process.
	Parameters
	----------
	app : Sphinx
	Sphinx application instance.
	exception : Exception
	Exception raised during the build process, if any.
	"""
	if exception:
	return
	search_index_list = []
	static_search_options = app.config.html_theme_options.get("static_search", {})
	excluded_docs = static_search_options.get("files_to_exclude", [])
	included_docs = app.env.found_docs
	for exclude_doc in excluded_docs:
	exclude_doc = Path(exclude_doc).resolve()
	# Exclude documents based on whether exclude_doc is a folder or a file:
	# - For folders, exclude all documents within the folder.
	# - For files, exclude only the exact file match.
	included_docs = [
	doc for doc in included_docs if not Path(doc).resolve().is_relative_to(exclude_doc)
	]
	for document in included_docs:
	pattern = get_pattern_for_each_page(app, document)
	search_index = SearchIndex(document, app, pattern)
	search_index.build_sections()
	search_index_list.extend(search_index.indices)
	search_index_path = Path(app.builder.outdir) / "_static" / "search.json"
	with search_index_path.open("w", encoding="utf-8") as index_file:
	json.dump(search_index_list, index_file, ensure_ascii=False, indent=4)

[jorgepiloto]

However, this is strange since other libraries have migrated to v1.2.1 and have no issues. Even when the exclude_doc is not defined in their conf.py.

[Andy-Grigg]

This is certainly a strange issue. The PyGrantaJobQueue documentation builds file with the ^1.2 release, but bomanalytics and RecordLists fail. I can't think of any significant differences between these documentations.

[Revathyvenugopal162]

This is certainly a strange issue. The PyGrantaJobQueue documentation builds file with the ^1.2 release, but bomanalytics and RecordLists fail. I can't think of any significant differences between these documentations.

This issue occurred because of the grantami template used for the API reference, which we didn’t account for template parsing while creating json file. I’ve added the necessary changes in PR #586 and working in https://github.com/ansys/grantami-bomanalytics/actions/runs/11896275334/job/33148530429?pr=644
