RuntimeError: Parameters must be a dict (hashtag2856)

[vikramsubramanian]

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

hashtaghashtag Code

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

storage_context = StorageContext.from_defaults(graph_store=graph_store)

hashtag 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)

RuntimeError: Parameters must be a dict

Summary: The code is throwing a RuntimeError "Parameters must be a dict" while executing in Colab.

Possible Solution

Based on the provided information, the issue is that the execute method in connection.py is expecting a dictionary for its parameters argument, but it is receiving a non-dict type, which leads to a RuntimeError: Parameters must be a dict. To resolve this issue:

• Ensure that every call to the execute method of the Connection class provides a dictionary for the parameters argument.
• Check the code where KnowledgeGraphIndex.from_documents is called and ensure that the parameters passed to any subsequent execute method calls within this function are in the correct dictionary format.
• If the parameters are being constructed dynamically, add validation to ensure that the final value passed to execute is a dictionary.
• If the error occurs in a specific scenario, such as when certain arguments are passed to KnowledgeGraphIndex.from_documents, add checks and error handling to manage these cases.

Here is an example of how to correctly call the execute method with a dictionary for the parameters:

conn.execute("MATCH (a:person) WHERE a.registerTime = $1 RETURN COUNT(*);", {"1": datetime.datetime(2011, 8, 20, 11, 25, 30)})

Make sure that all calls to execute follow this pattern and that the parameters are indeed a dictionary.
