Error with upload to Shiny Server

[danmalter]

The package works fine for me on my local machine, but when I try to upload it to an app using Shiny Server, I get the following error.

Loading required package: ipapi
Loading required package: data.table
Error : objects ‘winProgressBar’, ‘getWinProgressBar’, ‘setWinProgressBar’ are not exported by 'namespace:utils'

Package data.table automatically gets loaded as it is a requirement for ipapi.
