osmnx マップにルートをプロットしたい。ルートを手動で作成しようとすると、うまくいきません。
import networkx as nx
import osmnx as ox
import requests
import matplotlib.cm as cm
import matplotlib.colors as colors
location_point = (50.345559621674596, 7.576892382877531)
G = ox.graph_from_point(location_point, distance=500,
distance_type='network', network_type='walk')
origin_node = ox.get_nearest_node(G, location_point)
destination_node = list(G.nodes())[-1]
fig, ax = ox.plot_graph(G)
G=nx.convert_node_labels_to_integers(G)
route = [3 ,1 ,41 ,40 ,98 ,62 ,67 ,107 ,94 ,83 ,39 ]
ox.plot_route_folium(G,route)
色付きのルートを含むマップを期待していますが、代わりにこのエラーが発生します。

最短経路アルゴリズムでルートを見つけて地図上に視覚化しようとすると、うまくいきます。しかし、私はこの特定のルートをプロットしたい
