Error 137, "The application failed to start" // Show a Leaflet Map.

Hello, I ve the message "An error has occured" when I try to launch the leaflet page that I ve created.
The message is : Error 137, "The application failed to start"
The time seems too be long before to get the message. More than 15 secondes
(I ve too a warning about 'reticulate' which is "remplaced" by .GlobalEnv.)

I use a Slq request to get the data from my PostgreSql database.

df_postgresUsersLeafLet <- dbGetQuery(con, "SELECT distinct instance_id,first_name,last_name,gender,postcode,latitude,longitude,moving_date,city,'D' as Demenagement from core.users inner join core.address on 
                                      where core.address.latitude>41 and core.address.latitude<51 and core.address.longitude>-5.5667 and core.address.longitude<8.5316" )

Regroupement<-df_postgresUsersLeafLet%>% count(instance_id,latitude,longitude,city)

ui <- fluidPage(

server <- function(input, output, session) {
    ERA <- Regroupement %>%filter(instance_id=="eraimmobilier")
    SERGIC <- Regroupement %>%filter(instance_id=="sergic")
        output$mymap <- renderLeaflet({
        leaflet(Regroupement) %>% 
             addTiles() %>% 
               group = "eraimmobilier",
               color = "#a500a5", fillOpacity = 0.1)%>% addCircles(data=SERGIC,
                           group = "sergic",
                           color = "#a500a5", fillOpacity = 0.1)%>%addLayersControl(
                    overlayGroups = c("eraimmobilier", "sergic"),
                    options = layersControlOptions(collapsed = FALSE))
shinyApp(ui, server)

Do you have an idea about what is bad with that. ?

Can you show the logs of your app? that could tell us where to start looking for problems.

Hello I ve put the application with a "" Application, I don't find on the dashboard if I can get a log.
Is there a way to get it.
Thank you.

They are located here

Hello, this is the log, thanks you for your presentation of the correct way.

It seems you are running out of memory if you are on the free plan, you are under heavy memory and processing power limitations.
