Error in deploying shinyapp using leaflet and googlesheets API

I am working on a shinyapp that works locally, but throws an error everytime I try to publish it on shinyapps.io.

I have published apps using leaflet and they work, and I have also used googlesheets in other apps and that package works fine too. But when I use them altogether the app returns Error : there is no package called ‘leaflet’. Which is strange, because in this example app it does find the package.

leaflet working:

library(shiny)
library(leaflet)

# UI 
ui <-(fluidPage("Example", leafletOutput("map")))

# Server 
server = (function(input, output) {
  output$map   <- renderLeaflet({
      leaflet()    %>% 
        addProviderTiles("CartoDB.Positron")   %>% 
        setView(-58.43152, -34.6052, zoom=11 )    
  })
})

shinyApp(ui = ui, server = server)

leaflet not working:

library(shiny)
library(leaflet)
library(googlesheets)
library(sp)
library(rgdal)
library(DT)

options("googlesheets.httr_oauth_cache" = "gs_auth")
gs_auth()
rdv <- gs_url("https://docs.google.com/spreadsheets/d/1eWxmy7kSjWVfloJiS4ycjn4YKx2OybIzWogX7ga4fUQ/edit?usp=sharing", lookup = NULL, visibility = NULL, verbose = TRUE)

shape  <- readRDS("shape_ok.rds")
bounds <- bbox(shape)

sheet <- gs_read(rdv, ws = 3)


# UI
ui <-(fluidPage("Example", 
                  leafletOutput("map"),
                  dataTableOutput("table")
               )
)

# Server
server = (function(input, output) {

  output$map   <- renderLeaflet({
      leaflet(shape)    %>% 
        addProviderTiles("CartoDB.Positron")    %>% 
        setView(-58.43152, -34.6052, zoom=11 )  %>%
        addPolygons(stroke = T, fillOpacity = 0.65, smoothFactor = 0.5)
  })

  output$table <- renderDataTable({ as.data.frame(sheet) })

})

# Run the application 
shinyApp(ui = ui, server = server)

I have also deployed apps using googlesheets only and they work. So I have no clue of what's going on when I use both packages and get the leaflet error.

Solution

I downloaded an Argentinian RDS file and got it to work locally without changes (albiet with warnings). I also sucessfully published it to shinyapps.io at this URL:https://mikewise2718.shinyapps.io/Argentina/

I used RStudio version: 0.99.903

So it might be some kind of version problem, here is my sessionInfo():
