Hi 

I am creating JWT token on server side and getting the access_token from Box. GET users is working fine with that token.

But when I try to create a managed user, I am getting the below error. Even I tried to create user from here and I m getting the same error.

{
  "type": "error",
  "status": 400,
  "code": "invalid_request_parameters",
  "help_url": "http://developers.box.com/docs/#errors",
  "message": "Invalid input parameters in request",
  "request_id": "nz1zokhll68duz1d"
}
