Example Code for texture_image() produces an empty raster

[BlueGrisGris]

Hello,
Just started looking into geodiv for my research. When I tried to run the example code for texture_image(), I get a raster filled with Inf. This also occurs when I apply the function to my own data.
Example:

> help(texture_image)
> 
>      # import raster image
>      data(normforest)
>      normforest <- terra::unwrap(normforest)
>      
>      # crop raster to smaller area
>      x <- terra::crop(normforest, terra::ext(normforest[1:100, 1:100, drop = FALSE]))
>      
>      # get a surface of root mean square roughness
>      sa_img <- texture_image(x = x, window = 'square',
+      size = 5, metric = 'sa',
+      parallel = TRUE, ncores = 1, nclumps = 20)
[1] "Beginning calculation of metrics over windows..."

>      terra::plot(sa_img)

Thanks!

I am having the same issue. It seems to occur with some surface metrics and not others.
