Something wrong with calculating shortest paths

Describe the bug When I calculating shortest paths based on point sf and linestring sf, st_network_paths can't get the path and it warns me In shortest_paths(x, from, to, weights = weights, output = "both", : At core/paths/dijkstra.c:446 : Couldn't reach some vertices.

Reproducible example Sorry, i'm new to the reprex package,so i use the traditional way to give anexample~

the example data is here

library(sf)
library(tidygraph)
library(tidyverse)
library(sfnetworks)

plan = read_sf('demo.gpkg',layer='plan') 
road = read_sf('demo.gpkg',layer='road')

net = road %>% 
  as_sfnetwork(directed = FALSE) %>%
  activate("edges") %>%
  mutate(weight = edge_length())

paths = st_network_paths(net, from = plan[1,], to = plan[3,], weights = "weight")
paths
