I'm upgrading an app that uses llama-index==0.5.40 to llama-index==0.6.11. Using the example below, the entire contents of a 3 page test PDF are added to the index in the 0.5.4 version, but only the first page in 0.6.11. I've looked through the docs but any hints or suggestions are welcome. With the upgrade I also updated PyPDF2==3.0.1. to pypdf==3.9.0
index = GPTVectorStoreIndex([], service_context=service_context)
document = SimpleDirectoryReader(input_files=[doc_text]).load_data()[0]
index.insert(document)
