"timedatectl had status 1" error in shinyapps.io

shinyappsio

#1

An app that I've deployed on Shinyapps.io has an intermittent error. This is what I see in the logs, when I downloaded them from the console:

2018-08-21T16:47:54.113822+00:00 shinyapps[399820]: Failed to create bus connection: No such file or directory
2018-08-21T16:47:54.114373+00:00 shinyapps[399820]: Warning in system("timedatectl", intern = TRUE) :

2018-08-21T16:49:23.721652+00:00 shinyapps[399820]: Warning: Error in if: missing value where TRUE/FALSE needed

That's not my code. Reconnecting the client did resolve the issue, but I'd prefer not to have users see an error in the first place (and likely bounce). Any ideas what's going on?

What version of the Shiny package are you using? Or generally, what is the output of rsconnect::appDependencies()?

This would appear to be an issue with R itself.

As such, I would focus on the warning/error (kind of silly that it is in question):
