We were not able to run the Shiny app. The app is getting into disabled mode. Attached test application in execution mode.
Sample script which we ran.
library(shiny)
ui <- fluidPage(
textInput("name", "What is your name?"),
actionButton("greet", "Greet"),
textOutput("greeting")
)
server <- function(input, output, session) {
output$greeting <- renderText({
req(input$greet)
paste0("Hello ", isolate(input$name), "!")
})
}
shinyApp(ui, server)
Please find below attached image for reference.
Let me know if need additional info to troubleshoot further.
