RuntimeError: Parameters must be a dict

[goodrahstar]

Hi Team, I am facing issue with the interface.
Can someone help me with this error. I am running this in colab.

Code

documents = SimpleDirectoryReader("/content/data").load_data()
from llama_index.storage.storage_context import StorageContext

storage_context = StorageContext.from_defaults(graph_store=graph_store)

# NOTE: can take a while!
index = KnowledgeGraphIndex.from_documents(documents=documents,max_triplets_per_chunk=2,storage_context=storage_context,service_context=service_context,show_progress=True)

Hi @goodrahstar,

The interface of kuzu has changed quite a bit since we implemented the integration with LlamaIndex, so this integration no longer works with latest version of kuzu. You can fix this by downgrading kuzu to version 0.0.6: pip install kuzu==0.0.6. We will work on updating the integration and create a PR to LlamaIndex repo to make it work with the latest version of kuzu.

Thank you @mewim , Downgrading worked. Appreciate your prompt response. :)
