How can I get Pickle ML model from Minio and send it as a fastapi response as an API?

This code i am running to return pickle model to fastapi but its throwing error. How can i pass pickle model by connecting to minio

@app.post(f"{ROOT_PATH}/model/")
async def get_model():
    mlflow.set_tracking_uri("xxxxx")
    client = Minio("xxxxxx")
    bucket="mlflow"
    path="6/d344njdnjndkdkj/artifacts/model/model.pkl"
    ss = client.get_object(bucket, path, "model.pkl")
    return ss

Its throwing error in fastapi docs
