Error when debugging Arduino OPTA

Official Hardware Opta
1

I downloaded the latest version of Arduino IDE (2.3.2) from the Arduino website, installed Opta mbed in Boards Manager then connected via USB my Arduino Opta, when I click "start debugging" I get this

I tried to debug the following code

/**
  Getting Started with Opta™
  Name: LED_Blink_Opta
  Purpose: Blink STATUS LEDs on Opta™.

  @author Arduino
*/

void setup() {
  pinMode(LED_D0, OUTPUT);
  pinMode(LED_D1, OUTPUT);
  pinMode(LED_D2, OUTPUT);
  pinMode(LED_D3, OUTPUT);
}

void loop() {
  digitalWrite(LED_D0, HIGH);
  delay(100);
  digitalWrite(LED_D0, LOW);
  delay(100);

  digitalWrite(LED_D1, HIGH);
  delay(100);
  digitalWrite(LED_D1, LOW);
  delay(100);

  digitalWrite(LED_D2, HIGH);
  delay(100);
  digitalWrite(LED_D2, LOW);
  delay(100);

  digitalWrite(LED_D3, HIGH);
  delay(100);
  digitalWrite(LED_D3, LOW);
  delay(500);
}

I think I managed to load the program to the Arduino OPTA since the lights are flashing but I cannot debug.

Because the Opta apparently doesn't have a debugger. One fix is to pop it open and connect an ST-LINK debugger to it and then you should be good.
