exit status 1 troubleshoot

Hi there, still trying to run my first app:

Have made some very nice apps run locally. Still struggling to deploy. I have tried the old faithful data and even simpler stuff than that:

library(shiny)

# Define UI for application that draws a histogram
ui <- fluidPage(

    # Application title
    titlePanel("Hello Briday"),
)

# Define server logic required to draw a histogram
server <- function(input, output) {

}

# Run the application 
shinyApp(ui = ui, server = server)
library(rsconnect)
#rsconnect::setAccountInfo(name='briday', token='mytoken', secret='mysecret')
deployApp()

which gives me the error occured - exit status one. When i run tests this is the output:

Preparing to deploy application...Timing stopped at: 7.508 1.976 14.78
Error in `value[[3L]]()`:

 8.               └─rlang::abort(conditionMessage(x))

Exited with status 1.

Can someone help with this interpretation? Is this something to do with my directory?

Thanks in advance
