i want to download map data from osmnx to use it in (kepler.gl)[https://kepler.gl/demo]
but it only accepts data in csv,json and geojson format.
i have tried
import osmnx as ox
G = ox.graph_from_place('taian,shandong', network_type='drive')
ox.plot_graph(G)
nodes,edges=ox.graph_to_gdfs(G)
nodes.to_file('nodes_.geojson',driver='GeoJSON')
edges.to_file('edges_.geojson',driver='GeoJSON')
but edges occurs error
"invalid field type class:'list'"
how can i get csv or json or geojson from osmnx?
