I'm trying to deploy the official Shiny tutorial example "Hello Shiny" to my shinyapps.io account, but I keep hitting this error:

Error in `$<-.data.frame`(`*tmp*`, "config_url", value = "https://www.shinyapps.io/admin/#/application/") : 
  replacement has 1 row, data has 0

Here's the full code for my app.R file:

library(shiny)
ui <- fluidPage(
  titlePanel("Hello Shiny!"),
  sidebarLayout(
    sidebarPanel(
      sliderInput(inputId = "bins", label = "Number of bins:", min = 1, max = 50, value = 30)
    ),
    mainPanel(
      plotOutput(outputId = "distPlot")
    )
  )
)
server <- function(input, output) {
  output$distPlot <- renderPlot({
    x <- faithful$waiting
    bins <- seq(min(x), max(x), length.out = input$bins + 1)
    hist(x, breaks = bins, col = "#75AADB", border = "white",
         xlab = "Waiting time to next eruption (in mins)",
         main = "Histogram of waiting times")
  })
}
shinyApp(ui = ui, server = server)

Additional Context #

• The app runs flawlessly on my local machine.
• I'm working in a proxy environment and have followed all official configuration guidelines for shinyapps.io and the rsconnect package.
• Operating System: Windows 10
• All relevant packages (shiny, rsconnect, rmarkdown) are updated to their latest available versions.
• I get the exact same error when attempting to deploy a flexdashboard that uses a Shiny runtime.

Here's my sessionInfo() output for reference:

I've been troubleshooting this for a while without luck, so any tips or solutions would be greatly appreciated. Thanks in advance!
