Getting the RStudio Connect shiny app's downloadHandler to save plotly figures

Hi,
I have a shiny app that I'm publishing to an RStudio Connect server and I would like to have the option to download as PDFs the plotly figures that the app generates (in a reactive called out.plot())

This is the downloadHandler code I'm using:

  output$savePDF <- downloadHandler(
    filename = function() {
      paste0("figure_", Sys.Date(),".pdf")
    },
    content = function(file) {
       plotly::orca(out.plot(),file=file)
    }
  )

But on the Connect Server clicking the save button results with the error:
Error in : The orca command-line utility is required for this functionality.

I do have the orca-1.3.1.AppImage executable in the app code directory, which I'm including in the list of files I'm publishing, but I guess I need to point to it somehow so that it will be found on the Connect server.

Any idea?

Hi,

Have you tried putting the orca executable on the Connect server?
