409 Error When Uploading File via Python

I am just starting with Box, but after following the API and guides, my Python code will not correctly upload a file to Box. My code is as follows:

from boxsdk import JWTAuth
from boxsdk import Client
import json

# Read in JSON
with open('boxConfig.json') as f:
	data = json.load(f)

#Configure a JWT auth object
sdk = JWTAuth(
	client_id=data["boxAppSettings"]["clientID"],
	client_secret=data["boxAppSettings"]["clientSecret"],
	enterprise_id=data["enterpriseID"],
	jwt_key_id="MyIDHere",
	rsa_private_key_file_sys_path="./private_key.pem",
	rsa_private_key_passphrase="MyPassphraseHere",
)

# Get auth client
client = Client(sdk)


# Set upload values
file_path = './name.txt'
folder_id = '0'

box_file = client.folder(folder_id).upload(file_path)

and the error I get is 

boxsdk.exception.BoxAPIException:
