TinyObjReader and can't show the 3D figure in Rstudio [BUG]

[fermidq]

Describe the bug My environment is Ubuntu 22.04.1 LTS, with R 4.1.2 and Rstudio Server 2022.08.2 Build 576. I tried the example of "volcano" in the "readme.md" file and other my own dataset. In the last, when running "render_snapshot()", it shows "TinyObjReader: Degenerated face found" and only the gray bottom is shown. The colored line and topography is not shown. With my own data, the same error is shown.

Following is my code.

library(rayshader)
library(reshape2)
#Contours and other lines will automatically be ignored. Here is the volcano dataset:

ggvolcano = volcano %>% 
  melt() %>%
  ggplot() +
  geom_tile(aes(x = Var1, y = Var2, fill = value)) +
  geom_contour(aes(x = Var1, y = Var2, z = value), color = "black") +
  scale_x_continuous("X", expand = c(0, 0)) +
  scale_y_continuous("Y", expand = c(0, 0)) +
  scale_fill_gradientn("Z", colours = terrain.colors(10)) +
  coord_fixed()

plot_gg(ggvolcano, multicore = TRUE, raytrace = TRUE, width = 7, height = 4, 
        scale = 300, windowsize = c(1400, 866), zoom = 0.6, phi = 30, theta = 30)
Sys.sleep(2)
render_snapshot(clear = TRUE)
#Your code goes below

So how can resolve this problem?
