Getting the ST Link v3 MINIE to work

I am having a difficult time getting debug working on my Arduino Giga R1.

This is my sketch using MBED OS in Arduino IDE:

#include "mbed.h"
#include "USBSerial.h"

using namespace mbed;
using namespace rtos;

USBSerial serial;
DigitalOut led(LED1);

int main(void) {
  while(1) {
    printf("changing led");
    led = !led;
    thread_sleep_for(1500);      
  }
}

When I select the correct port, and hit board info I get:

I downloaded STM32 Cube Programmer, and upgraded the firmware.

11:40:40 : ST-LINK SN  : 002600453033510635393935
  11:40:40 : ST-LINK FW  : V3J13M4
  11:40:40 : Board       : STLINK-V3MINIE
  11:40:40 : Voltage     : 3.24V

When I attempt to debug, I get:

I have the jtag connected as follows:

I followed the following guide to connect the JTAG (page 11):
STLINK-V3MINIE debugger/programmer tiny probe for STM32 microcontrollers - User manual

It indicates that even though the cable is 14 pin for the STLINK v3 MINIE, for 10 pin connections, you leave 2 pins on either side hanging off the plug. PIN #3 on the ST LINK v3 MINIE is PIN #1 on the Arduino Giga JTAG. The Giga datasheet ( ABX00063-datasheet.pdf (arduino.cc)) seems to indicate that connector J8 on the board has its pin #1 indicated by the *.

Any ideas why this is not working is greatly appreciated!

EDIT: Forgot to mention I am using IDE:
