shinylive fails on trailing comma in UI, where shiny is ok with it

[daniel-simeone]

library(shiny)
ui <- fluidPage(
  tagList(h1("hello"), 
             )
          )
server <- function(input, output) { }
shinyApp(ui = ui, server = server)

This extremely simple shiny app works fine in shiny. Notice the trailing comma after the h1().

It compiles/translates to shinylive no problem. But when you run it from the static site, it gets this:

Clearly, the comma is a problem at run time for shiny live, but not for shiny.

Interestingly, it isn't a problem on shinylive.io.

library(shiny)
ui <- fluidPage(
  tagList(h1("hello"), )
)
server <- function(input, output) { }
shinyApp(ui = ui, server = server)

In that case, perhaps this is useful: Tested on Chrome - Version 131.0.6778.108 (Official Build) (64-bit)
