Camera board • Camera is not able to click the images

I am currently running the python script on Raspberry Pi 4 Model B Rev 1.2 and i have enabled the camera legacy in raspi configuration
and the python script is:

from time import sleep
from datetime import datetime
import subprocess


dir = "define the folder path"

while True:
fileName = "img_" + datetime.now().strftime("%d/%m/%Y, %H:%M:%S")


# Capture image
cmd = "libcamera-jpeg -t 1000 --shutter 2000 --gain 8 --width 3280 --height 2464 --output=" + dir + fileName + ".jpg" #here i have changed the time from 100 milliseconds to 50 milliseconds
subprocess.call(cmd, shell=True)

sleep(5)

It gives me this error when i run this command. I have tried changing the configuration manually by setting camera_auto_detect=0, dt_overlay=imx219 but it doesn't work
