R Shiny script, checkbox and save

I have a problem with my script below, in fact when recording the status of checkboxes, I would like to have True if the checkbox is checked otherwise False, because for now I just have or . This is my script on R :

library(shiny)
library(shinythemes)
library(leaflet)
library(DT)
library(leaflet.extras)
library(readxl)
library(purrr) 
library(htmlwidgets)
library(magrittr)

library(sf)
library(htmltools)

Boccurrence1 <- rbind(Boccurrence, Boccurrence2)


lng1 <- -12
lat1 <- 39
lng2 <- 13
lat2 <- 52

taxon_data <- read_excel("species.xlsx")
species_names <- taxon_data$species

output_directory <- "map"


zee <- st_read("zee.shp")

zee <- st_transform(zee, crs = st_crs("+proj=longlat +datum=WGS84"))

shinyApp(ui = ui, server = server)

I tried this code but as soon as I save the page it closes and doesn't work anymore.

observeEvent(input$save_button, {
  event <- input$map_marker_click
  if (!is.null(event$id)) {
    selected_row <- filtered_occurrences1()[filtered_occurrences1()$id == event$id,]
    complete_cases <- complete.cases(selected_row$id)
    selected_row <- selected_row[complete_cases,]

    if (input[[paste0("suppression_", selected_row$id)]] == "on") {
      selected_row$Suppression <- "Suppression"
    } else {
      selected_row$Suppression <- ""
    }

    if (input[[paste0("inversion_", selected_row$id)]] == "on") {
      selected_row$Inversion <- "Inversion"
    } else {
      selected_row$Inversion <- ""
    }

    current_selected_rows <- selected_rows()
    current_selected_rows[[length(current_selected_rows) + 1]] <- selected_row
    selected_rows(current_selected_rows)
  }
})

I've also tried this, but it gives me the same error and I don't understand.

selected_rows <- reactiveVal(list())

observeEvent(input$map_marker_click, {
  event <- input$map_marker_click
  if (!is.null(event$id)) {
    selected_row <- filtered_occurrences1()[filtered_occurrences1()$id == event$id,]
    complete_cases <- complete.cases(selected_row$lat, selected_row$lng)
    selected_row <- selected_row[complete_cases,]

    selected_row$Suppression <- paste0(
      '<input type="checkbox" id="suppression_', selected_row$id, '" name="suppression_', selected_row$id, '">'
    )
    selected_row$Inversion <- paste0(
      '<input type="checkbox" id="inversion_', selected_row$id, '" name="inversion_', selected_row$id, '">'
    )

    current_selected_rows <- selected_rows()
    current_selected_rows[[length(current_selected_rows) + 1]] <- selected_row
    selected_rows(current_selected_rows)

    output$table <- renderDataTable({
      datatable(
        selected_row,
        escape = FALSE,
        options = list(rowId = "id")
      )
    })
  }
})

observeEvent(input$save_button, {
  event <- input$map_marker_click
  if (!is.null(event$id)) {
    selected_row <- filtered_occurrences1()[filtered_occurrences1()$id == event$id,]
    complete_cases <- complete.cases(selected_row$lat, selected_row$lng)
    selected_row <- selected_row[complete_cases,]

    selected_row$Suppression <- ifelse(
      input[[paste0("suppression_", selected_row$id)]] == "on",
      "TRUE",
      ""
    )
    selected_row$Inversion <- ifelse(
      input[[paste0("inversion_", selected_row$id)]] == "on",
      "TRUE",
      ""
    )

    current_selected_rows <- selected_rows()
    current_selected_rows[[length(current_selected_rows) + 1]] <- selected_row
    selected_rows(current_selected_rows)
  }
})
