I have a problem with plot contour lines using st_as_sf() in shinyapps.io. I checked all the packages' dependencies and nothing. I know that's in st_as_sf() because in my all data set, some contour plot works and don't have any geometry problem with my stands_extent file.
My plot works very well in local Shiny RStudio. But after publishing on shinyapps.io:
My example below and just only with Unique ID CERROCOROADO_003A the plot work:

setwd(tempdir())
stands_extent <- readOGR(".", "stands_target") # Border
stands_ds <- read.csv("pred_target_stands.csv", sep=";") # Data set
stands_ds <- stands_ds %>%
mutate(DATA_S2 = ymd(DATA_S2))
# Create the shiny dash
ui <- fluidPage(
theme = shinytheme("cosmo"),
titlePanel(title="My Map Dashboard"),
sidebarLayout(
sidebarPanel(
selectInput(inputId = "selectedvariable0",

choices = c(unique(stands_ds$PEST)),selected = TRUE ),
selectInput(inputId = "selectedvariable1",

),
mainPanel(

fluidRow(
splitLayout(plotOutput("myplot"))),
dateInput(inputId = "Dates selection", label = "Time")
)
)
)
server <- function(input, output){
currentvariable0 <- reactive({input$selectedvariable0})
currentvariable1 <- reactive({input$selectedvariable1})
currentvariable2 <- reactive({input$selectedvariable2})
currentvariable3 <- reactive({input$selectedvariable3})
currentvariable4 <- reactive({input$selectedvariable4})
output$myplot <- renderPlot({
#Subset stand
stands_sel <- subset(stands_extent, stands_extent@data$ID_UNIQUE==currentvariable4())
#Subset for input$var and assign this subset to new object, "fbar"
ds_sel<- stands_ds[stands_ds$ID_UNIQUE==currentvariable4(),]
#Create a map
polys <- st_as_sf(stands_sel)
ggplot() +
geom_sf(data=polys) +
geom_point(data=ds_sel,
aes(x=X, y=Y), color="red") +
xlab("Longitude") + ylab("Latitude") +
coord_sf() +
theme_bw() +
theme(text = element_text(size=10))
})
}
shinyApp(ui, server)

Please, any idea for fix it?
