Problem: I'm trying to upload files into BOX folder using JWT Authentication by making use of Box Sdk's (https://github.com/box/box-python-sdk-gen/blob/main/docs/authentication.md)

Error: I get the following error which says " FoldersManager" object is not callable when I use the following syntax.

new_file = client.folders(folder_id).upload('')

Code:

import json
import requests
from box_sdk_gen.client import BoxClient
from box_sdk_gen.jwt_auth import JWTConfig , BoxJWTAuth

jwt_config = JWTConfig.from_config_file('/Users/xxxx/Desktop/xxxx /config.json')

auth = BoxJWTAuth(config=jwt_config)
user_auth = auth.as_user('3831914027')
client = BoxClient(user_auth)
folder_id = '223389277713'


new_file = client.folders(folder_id).upload('/Users/xxxx/Desktop/xxxx /xxxx/part-00000-c69946d5-6a92-499f-8fec-01d06e48e6ca-c000.csv')
