'error Not joystick'

Hi every one.
I'm trying to send command like:

But after some commands like this:

from djitellopy import Tello
import time
tello = Tello()
tello.connect()
tello.takeoff()
tello.move_forward(100)
time.sleep(0.5)
tello.rotate_clockwise(90)
time.sleep(0.5)
tello.move_forward(100)
time.sleep(0.5)
tello.rotate_clockwise(90)
time.sleep(0.5)
tello.move_forward(100)
...
tello.land()

I received the 'error Not joystick' error.

Thanks to the library, and any assistance will be appreciated.

My terminal:

Hey Fernando, long time no see 😎

Please try calibrating the drone using the official app. After connecting to your drone using your phone you can start the calibration procedure from the Tello App settings menu.
The app will then guide you through calibration (taking of the rotors and placing the drone in different positions).

Cheers Jakob
