Sidebar open parameter crash Shinylive when passing a list

[cedricbouffard]

When passing a list to the open parameter in a sidebar, shinylive will display this error:

I tried with a named character vector, same problem.

Here's a sample code:

library(shiny)
library(bslib)

ui <- page_sidebar(

  sidebar = sidebar(
    open = list(desktop = "always", mobile = "open")
  ),
  mainPanel(
    "Test"
  )
)

server <- function(input, output, session) {
 
  }
  


shinyApp(ui, server)

I wonder if there's an encoding issue? I just copied your example into shinylive and it worked as expected. (I edited it lightly in that link but the direct copy works as well.)

I noticed that the error message appears to say

Error: `open` must be one of "desktop", "open", "closed", or "always", not "always".

which seems to indicate there's a difference between "always" and "always"?

Oh, actually I think I found the bug! I'm not sure which exact conditions produce the error, but I ran into it myself and know how to fix it :)
