[Python] PyGame: Use SDL2 to render a pixel

I want to render a singular green pixel in PyGame with SDL2. This is my current code:

import pygame
import pygame._sdl2

SCREEN_W = 800
SCREEN_H = 800

pygame.init()

pygame_screen = pygame.display.set_mode((SCREEN_W, SCREEN_H), vsync=0, flags=pygame.SCALED)
window = pygame._sdl2.Window.from_display_module()

renderer = pygame._sdl2.Renderer.from_window(window)
renderer.draw_color = (0, 255, 0, 255) # Set the draw color to green

clock = pygame.time.Clock()

scale_factor = 1

# Create a green surface
green_pixel = pygame.Surface((scale_factor, scale_factor))
green_pixel.fill((0, 255, 0, 255))

use_sdl2 = True

while True:
msec = clock.tick(60)
pygame_screen.fill((0, 0, 0))

for event in pygame.event.get():
if event.type == pygame.QUIT:
pygame.quit()
quit()

if use_sdl2:
renderer.clear()
dest_rect = pygame.rect.Rect(100, 100, scale_factor, scale_factor)
renderer.blit(green_pixel, dest_rect)
renderer.present()
else:
dest_rect = pygame.rect.Rect(100, 100, scale_factor, scale_factor)
pygame_screen.blit(green_pixel, dest_rect)
pygame.display.flip()


This gives the following error:

Traceback (most recent call last):
File "/home/harald-yoga/Documents/Projects/Python/game-engine/src/game_engine/main.py", line 37, in <module>
renderer.blit(green_pixel, dest_rect)

TypeError: source must be drawable



The non-SDL2 version (use_sdl2 = False) works fine and renders a green pixel at x: 100, y: 100. What am I doing wrong with the SDL version?
