How to fix "Uncaught PDOException: ...Conversion failed when converting date and/or time from character string"?

I'm developing an event calendar using full-Calendar. I'm getting the above error after an event has been dropped on the calendar. It seems that the date format needs to be converted, I'm not sure exactly how should I do that. In one of my previous questions I was suggested that something like yyyy-mm-dd hh:mm would work better and that should be done using momentJs.

As I'm very new to js, I'm not sure how and what exactly should I change in my code.

Here's the code:

   document.addEventListener('DOMContentLoaded', function() {
  var Calendar = FullCalendar.Calendar;
  var Draggable = FullCalendarInteraction.Draggable;

  var containerEl = document.getElementById('external-events');
  var calendarEl = document.getElementById('calendar');
  var checkbox = document.getElementById('drop-remove');


 new Draggable(containerEl, {
    itemSelector: '.fc-event',
    eventData: function(eventEl) {
    return {
      title: eventEl.innerText
     };
   }
  });

 var calendar = new Calendar(calendarEl, {
 plugins: ['interaction', 'dayGrid', 'timeGrid'],
 header: {
   left: 'prev,next today',
  center: 'title',
  right: 'dayGridMonth,timeGridWeek,timeGridDay'
},
editable: true,
droppable: true,
eventReceive: function(info) {

  //get the bits of data we want to send into a simple object
  var eventData = {
    title: info.event.title,
    start: info.event.start,
    end: info.event.end
  };
  console.log(eventData);
  //send the data via an AJAX POST request, and log any response which comes from the server
  fetch('add_event.php', {
      method: 'POST',
      headers: {
        'Accept': 'application/json'
      },
      body: encodeFormData(eventData)
    })
    .then(response => console.log(response))
    .catch(error => console.log(error));
    }
 });
  calendar.render();
});

const encodeFormData = (data) => {
  var form_data = new FormData();

for (var key in data) {
   form_data.append(key, data[key]);
  }
  return form_data;
}

index.php

<div id='external-events'>
  <p>
<strong>Draggable Events</strong>
 </p>
 <div class='fc-event'>My Event 1</div>
  <div class='fc-event'>My Event 2</div>
  <div class='fc-event'>My Event 3</div>
  <div class='fc-event'>My Event 4</div>
  <div class='fc-event'>My Event 5</div>
  <p>
    <input type='checkbox' id='drop-remove' />
    <label for='drop-remove'>remove after drop</label>
  </p>
</div>
<div id='calendar-container'>

add_event.php

require 'connection.php';
    $title = $_POST['title'];
    $start = $_POST['start'];
    $end = $_POST['end'];
        $conn = DB::databaseConnection();
       $conn->beginTransaction();
$sqlInsert = "INSERT INTO Events ( title, start, [end]) VALUES ( :title, :start, :end)";
    $stmt = $conn->prepare($sqlInsert);
    $stmt->bindParam(':title', $title);
    $stmt->bindParam(':start', $start);
    $stmt->bindParam(':end', $end);
    if ($stmt->execute()) {
            $conn->commit();
            return true;
        } else {
            $conn->rollback();
            return false;
        }

    ?>

The event details needs to be saved in a ms-sql database. The function for that is in the add_event.php file. Please let me know if you would like to see the code for that too, will post that too.

If you're using momentJS, and, assuming you've included the momentJS file in your page already, then:

start:moment(info.event.start).format("YYYY-MM-DD HH:mm"),
end:moment(info.event.start).format("YYYY-MM-DD HH:mm" )

should do the trick. See https://momentjs.com/docs/#/displaying/format/ for details.
