[cr1g]

Simply put, the last line in the code below fails with the exception: TypeError: Object of type bytes is not JSON serializable.

from io import BytesIO

from sendbird_platform_sdk.api import user_api
from sendbird_platform_sdk.model.create_user_data import CreateUserData

with open("profile_picture.jpg", "rb") as profile_picture:
    profile_picture_stream = profile_picture.read()

api_instance = user_api.UserApi(api_client)
create_user_data = CreateUserData(
    user_id="random_guid",
    nickname="example_nickname",
    profile_url="",
    profile_file=BytesIO(profile_picture_stream),
    issue_access_token=True,
)
api_instance.create_user(
    api_token="MY_API_TOKEN", create_user_data=create_user_data
)
