When the face is replaced, a black and white image is obtained.

[anchsemen]

Using the API, I make base64 image format (target and source) And I make a request to the server where the SD with ReActor is located. But if I don't use the saved face_models, then I get black and white images. What am I doing wrong?
Also, the question is whether it is possible to create a new face model using the image API?
My code:
`with open("5.png", "rb") as image_file:
base64_string = base64.b64encode(image_file.read()).decode('utf-8')
with open("2.png", "rb") as image_file2:
result = base64.b64encode(image_file2.read()).decode('utf-8')

payload_reactor = {
"source_image": "data:image/png;base64," + base64_string, # I tried both with and without the addition of this line ("data:image/png;base64,")
"target_image": "data:image/png;base64," + result,
"source_faces_index": [0],
"face_index": [0],
"upscaler": "None",
"scale": 1,
"upscale_visibility": 1,
"face_restorer": "CodeFormer",
"restorer_visibility": 1,
"codeformer_weight": 0.5,
"restore_first": 1,
"model": "inswapper_128.onnx",
"gender_source": 0,
"gender_target": 0,
"save_to_file": 0,
"result_file_path": "",
"device": "CUDA",
"mask_face": 0,
"select_source": 0,
"face_model": "None",
"source_folder": "",
"random_image": 0,
"upscale_force": 0,
"det_thresh": 0.5,
"det_maxnum": 0
}

response = requests.post(url=f'{url}/reactor/image', json=payload_reactor)
r_reactor = response.json()
with open("output_reactor1.png", 'wb') as f:
f.write(base64.b64decode(temp))`

результат такой получается:
