Hi all!
I have a shiny app in a flexdashboard and locally it works well.
Now I want to put it online using Shiny Server, but it doesn't works 
The stranger thing is that it is related with the use of highcharter package. Because, a demo.rmd file work well, but not mi file (that use the highcharter package).
Even with this example file

I received the following error message (while deploying on shiny server)
I don't know what happened, or what is the problem. Locally, everything is ok 
Thanks.
