rasterLayer as internal/external data fail to load


I’ve successfully installed a small package from a source .gz file with an internal raster object. Everything went fine with installation, but the raster object cannot be handled in any operation. I've tried to put it as external data with:

usethis::use_data(clc2018, overwrite = T, internal = F)

But the error persists.

> install.packages("/cloud/project/landi_0.0.0.9000.tar.gz", repos = NULL)
