Debugging and error handling

[rezasz969]

Hi there,
I wrote a shiny web app and this app get a table from the database with an ID, but when I importing a ID does not exist in the data, it gives an error. I fixed this error with the tryCatch function. But this function does not work in Golem architecture and The whole app crashes and closes. how can I handling an error in golem?

A part of my code:

output$data <- renderDT({
      tryCatch({
      DT::datatable(r$data, rownames = F,
                    options = list(scrollX = T, fixedHeader = T,
                                   columnDefs = list(list(className = 'dt-center', targets = '_all'))))
      }, error = function(w) {
        shinyalert("Error!", w$message, type = "error")
        return()
      })
    })
