This is the same as e105befbe4ee0d85e94c2048a744f0373e2dbcdf on
additional place in the code.
When a link is pointing to location inaccessible to build user (e.g. "/root/something"),
filepath.is_file() throws "PermissionError: [Errno 13] Permission denied".
Fix this by first checking if it is a link.
