Are you using third party vector_store? If not then you can fetch all the nodes from Docstore like:
nodes = index.docstore.docs

Chroma does not provide the way to extract nodes in their Vector Store code: https://github.com/run-llama/llama_index/blob/main/llama_index/vector_stores/chroma.py

But if you are ingesting for the first time then it can be extracted like this
