I was able to resolve it, I am not sure if my steps are correct but i was able to program the nucleo 64 board. Below are the steps that I flowed to resolve the issue:

in file stlink/include/stlink/chipid.h line 60

• STLINK_CHIPID_STM32_L452 = 0x462,

in file stlink/src/chipid.c line 418

• {

•        // STM32L452RE
  

•       // From RM0393.
  

•        .chip_id = STLINK_CHIPID_STM32_L452,
  

•        .description = "L452RE device",
  

•        .flash_type = STLINK_FLASH_TYPE_L4,
  

•        .flash_size_reg = 0x1fff75e0,    // "Flash size data register" (sec 43.2, page 1410)
  

•        .flash_pagesize = 0x800,         // 2K 
  

•        .sram_size = 0x28000,
  

•        .bootrom_base = 0x1fff0000,      // (Bank 1 system memory)
  

•        .bootrom_size = 0x7000           // 28k (per bank)
  

•    },
  

in file stlink/src/flashloader.c line 308

• else if ((sl->chip_id == STLINK_CHIPID_STM32_L4) ||

•      (sl->chip_id == STLINK_CHIPID_STM32_L43X)||
  

•       (sl->chip_id == STLINK_CHIPID_STM32_L452))
  

Although i had to run command
~$ st-flash erase
before successfully programming the file.
