So I have been trying to authenticate the Box app with the Python SDK using JWT, but I am getting an error.

“BoxOAuthException:


Message: Please check the ‘sub’ claim. The ‘sub’ specified is invalid.


Status: 400


URL: https://api.box.com/oauth2/token


Method: POST”

I have crossed checked the “enterprise_id” value which is specified in the config file (the box account which I am currently using is a personal one, so the enterprise in this case was showing as ‘0’).

Also providing the python code which was written for this use-case:

from boxsdk import JWTAuth, Client

auth = JWTAuth.from_settings_file(‘/Users/pratyush/Downloads/0_pvp4byup_config.json’)


client = Client(auth)


service_account = client.user().get()


print(f’Service User Account id is {service_account.id}')
