rhub `rhub::check_for_cran()` giving me a note about finding a NULL file/directory

Hello, I was running rhub::check_for_cran() on my package to get it ready for CRAN, and I keep getting this note:

❯ On windows-x86_64-devel (r-devel)
  checking for non-standard things in the check directory ... NOTE
  Found the following files/directories:
    ''NULL''

However, I am unable to find this NULL file/directory anywhere, even with the ls -a in the terminal. I even deleted my local repo and re-cloned it, but this note persists.

I'm wondering if anyone has the same issue or if anyone has any insight at all. Thanks in advance, I would much appreciate it.

Probably an R-hub thing, so you can ignore it.

Thanks, I appreciate the response! I haven't been able to make this note go away but I will stop worrying about it now.

This issue is about the previous R-hub system, it does not apply to the new system, so I am closing it now. Please see https://r-hub.github.io/rhub/ for the new system, R-hub v2.
