I have a dashboard that uses shinyWidget package, when I run the dashboard locally, it works fine, however when I put the dashboard on R shiny server, an error occurs. I narrowed it down and it seems the problem is with the loading of shinyWidget package. I have an example available here. Any suggestions on how to fix load of the library, or what is causing this issue is appreciated.
R version 3.6.0 (2019-04-26) flexdashboard_0.5.2 shiny_1.5.0 shinyWidgets_0.6.0
