Im trying to make a POST request but it throws an error: {'error': 'HTTPException', 'detail': 'Invalid encoded image', 'body': '', 'errors': ''}

Thats how I'm trying to make a request:

photo = Image.open("photos/photo.png")
photo_b64 = base64.b64encode(photo.tobytes()).decode('utf-8')

payload = {
    "input_image": photo_b64,
    "detection_prompt": "car",
    "avoidance_prompt": "people",
    "positive_prompt": "",
    "negative_prompt": "",
    "width": 512,
    "height": 512,
    "sam_model_name": "sam_vit_h_4b8939.pth",
    "dino_model_name": "GroundingDINO_SwinT_OGC (694MB)",
    "seed": -1,
    "sampler": "DPM++ 2M SDE Karras",
    "steps": 20,
    "box_threshold": 0.3,
    "mask_expand": 35,
    "mask_blur": 4,
    "cfg_scale": 5.5,
    "denoise": 1,
    "inpainting_mask_invert": False,
    "upscaler_for_img2img": "",
    "fix_steps": False,
    "inpainting_fill": 0,
    "sd_model_checkpoint": "",
    "max_resolution_on_detection": 1280,
    "inpaint_padding": 40
}
response = requests.post(url=f'{url}replacer/replace', data=json.dumps(payload))

r = response.json()
print(response.json())        

image = Image.open(io.BytesIO(base64.b64decode(r['images'][0])))

Solved

photo_path = "photos/photo.png"

with open(photo_path, 'rb') as image_file:
    base64_bytes = base64.b64encode(image_file.read())
    base64_bytes = base64_bytes.decode('utf-8')
