  <p>I am calling an ajax call, which collects some ids and pass it to the custom action</p>
  
  <pre><code>$(".recalculate-bulk-charges").click(function(e){
        e.preventDefault();
        var booking_report_ids = []
        $(".booking_report_row input:checkbox:checked").map(function(){
          if (parseInt($(this).val()) != NaN) {
            booking_report_ids.push(parseInt($(this).val()));
          }
        });
        $.get("url", {"br_ids[]": booking_report_ids}).done(function(){
          window.location = "url";
        })
      }) 
  </code></pre>
  
  <p>When I restart my server, the error doesn't appear again. Please help me for the same.</p>
