Error in if for join-admin tutorial

[anelda]

Hi,

I just installed afrilearnr and get the following error message when I run:
learnr::run_tutorial("join-admin", "afrilearnr")

Listening on http://127.0.0.1:6081
Warning: Error in if: argument is of length zero
  72: ui

The app opens in the browser - see screenshot

Thanks,

Anelda

I've committed a change that may partially fix this. I can't replicate on my PC. @anelda can you try again ?

Hi there,

Cheers,

Warning: Error in if: argument is of length zero
  72: ui

and this opens in a browser window:
