Prep Error during rhub::check_for_cran

Package development
1

Hi Posit community,

I'm building an R package for the first time and ran into prep errors when doing the final check using rhub::check_for_cran().
Specifically, the check seems to work for Windows and Linux but fails for "Ubuntu Linux 20.04.1 LTS, R-release, GCC".
Moreover, it is not even clear what the error is for the prep failure in Ubuntu. Here is the email I received from rhub regarding the failure: (CoxAIPW 0.0.1 is my package name)

CoxAIPW 0.0.1: PREPERROR
Build ID: CoxAIPW_0.0.1.tar.gz-84328d7af8874d4d9a292f723057287d

Platform: Ubuntu Linux 20.04.1 LTS, R-release, GCC
Submitted: 3 hours 37 minutes 25.7 seconds ago
Build time: 1 hour 59 minutes 44.5 seconds

See the full build log: text, artifacts.

I also include below a successful check on windows from rhub:

Please let me know if anyone has any ideas why, thanks.

Unfortunately that's a bug in R-hub, and if the log is too long, then a successful check will turn into a prep error. If you look at the log, you'll see that the check is almost fine, you only get
