Hey folks,

Im under free developer license, trying to build app, which will access box to upload download files.

 

I cannot use OAuth, since this is part of pipeline flow. And I have to use box, since it’s part of SONY automation portal

 

I’m getting error ‘

*BoxOAuthException**: Message: Please check the 'sub' claim. The 'sub' specified is invalid.

Status: 400’

Is this because my enterprise account = 0? If so, any ways I can use JWT with free licence? Or what tier do I need to carry?
