I have a piece of code which provides the route from a source point to destination point. In the below code, origin_lat and origin_long are the source coordinates and dest_lat and dest_long are the destination coordinates

G = ox.graph_from_bbox(origin_lat,dest_lat,origin_long,dest_long, network_type='drive')
origin_point = (origin_lat, origin_long) 
destination_point = (dest_lat, dest_long)
origin_node = ox.get_nearest_node(G, origin_point,method='euclidean')
destination_node = ox.get_nearest_node(G, destination_point,method='euclidean')
route = nx.shortest_path(G, origin_node, destination_node, weight='travel_time')

But for some coordinates, I am not getting a complete route from source to destination. I have attached the screenshot of the output where I have plotted the route on ScatterMapbox image The black route is not reaching the source and destination, means the graph itself is incomplete. Can anyone help me out with this.
