I am working on knowledge graph and all connection to neo4j browser is a success(using neo4j desktop windows not docker deployed). however with llama3 i am running the same notebooks as in property graph construction with predefined schemas documentation.

all cells run with success except when the following code runs

from llama_index.core import PropertyGraphIndex
from llama_index.embeddings.huggingface import HuggingFaceEmbedding

index = PropertyGraphIndex.from_documents(
    documents,
    kg_extractors=[kg_extractor],
    embed_model=HuggingFaceEmbedding(model_name="BAAI/bge-small-en-v1.5"),
    property_graph_store=graph_store,
    vector_store=vec_store,
    show_progress=True,
)

It throws an error: ConnectError: All connection attempts failed

What i have done:

I have installed the APOC pluging, all apoc procedures looks good
All connections looks good

However, i still can’t figure out why i keep getting An error occurred while creating the PropertyGraphIndex: All connection attempts failed i try to parse the nodes and extract paths from text with schema.

Any Help on this will be greatly appreciated.
