[Python] How to export TopologicPy graph to Neo4j

I am trying to store a TopologicPy graph in Neo4j. I tried the codes below according to the TopologicPy documentation:

from topologicpy.Topology import Topology
from topologicpy.Graph import Graph
from topologicpy import Neo4j

IFC_file_path = "sample.ifc"
graph_topo = Graph.ByIFCPath(IFC_file_path)

username="..."
password="..."
url="..."

graph_neo4j = Neo4j.Neo4j.ByParameters(url=url, username=username, password=password)
topo_neo4j = Neo4j.Neo4j.AddGraph(neo4jGraph=graph_neo4j, graph=graph_topo, labelKey='None', relationshipKey='None')


But I got the error below. Anyone knows where the problem is? Are there some ways to store a TopologicPy graph to Neo4j? Thanks!
