Language file for DT not working in Shiny app hosted on RStudio Cloud

I would like to localize the DataTable that I use in my Shiny app. I would like the user interface to be in Dutch. The code underneath with a Dutch language file works fine on my laptop, but when I upload the code to RStudio Cloud the user interface of DataTable is in English. Why is this and how can I fix it?


bevingen <- bevingen <- read_csv("") 

header <- dashboardHeader(title = "Mijn eerste Shiny app!")

sidebar <- dashboardSidebar(disable = TRUE)

body <- dashboardBody(DTOutput(outputId = 'tabel'))

ui <- dashboardPage(header, sidebar, body)

server <- function(input, output) {
  dutch <- ""
  output$tabel <- renderDT(
                           options = list(language = list(url = dutch))

shinyApp(ui, server)
