When does this happen?

IF Loading documents from Elasticsearch/Opensearch where documents have empty or very short text content causes ValueError: 'Effective chunk size is non positive after considering extra_info' when building an index.

How others solved it

THEN Before passing documents to GPTVectorStoreIndex.from_documents(), ensure each document's text content has a minimum length (e.g., >0). Optionally, filter out documents with empty text or adjust chunk size and overlap parameters to handle short content. Validate that the text field specified in the reader actually contains data.

docs = reader.load_data(text_field)
docs = [d for d in docs if len(d.get_text()) > 0]
index = GPTVectorStoreIndex.from_documents(docs, storage_context=storage_context)
