Error in hillshade

[Joe-StPeter]

I hate to bother you, but I am running through this class, and thank you for it, and I am getting an error when I run the code:
hobart_mat %>%
lamb_shade(zscale = 33) %>%
add_shadow(ray_shade(hobart_mat, zscale = 33,
sunaltitude = 6, lambert = FALSE), 0.3) %>%
plot_map()

This is the error message:
Error in hillshade * t(scales::rescale(shadowmap[nrow(shadowmap):1, ], :
non-conformable arrays

Here is my sessionInfo()

Can you direct me how to solve this issue so that I can continue your tutorial?

I'm also following the tutorial (which is amazing, by the way) and am having the exact same problem. Everything worked until I got to this point.

This is my error message:

Error in hillshade * t(scales::rescale(shadowmap[nrow(shadowmap):1, ], :

Please help. Thank you!
