javascript - Issue displaying map highcharter shiny -

i met problems in displaying map in shiny using package highcharter. when try display in rstudio viewer, ok, map fine.

whereas, when try display in shiny app via functions highchartoutput(in server) , renderhighchart(in ui).

the "highcharter code" of map in pretty simple, , it's not problem because can display in viewer, show anyway here :

  carte <- highchart(type = "map") %>%     hc_title(text = "test") %>%     hc_add_series_map(map,as.data.frame(dat),value='n',joinby=c('name','lib_dep'))%>%     hc_mapnavigation( enablemousewheelzoom=t) -> carte    carte 

i bet problem comes .js libraries load, not sure it.

anyone me ?

thanks.
