"Error in value[[3L]](cond) : app.R did not return a shiny.appobj object

[subramaniamsmurugesa]

Error in value[3L] : app.R did not return a shiny.appobj object. Calls: local ... tryCatch -> tryCatchList -> tryCatchOne -> Execution halted"

This is the error i am getting while deploying my shiny app in shiny.io, but the app works fine in local machine. If some on can help me, i would really appreciate the help.

does your app conform to the following structure ?

library(shiny)

ui <- fluidPage(
  
)

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

shinyApp(ui, server)

I would expect to see your error if I omitted ShinyApp() function call
