Getting Null GUID on Create

[RailsCod3rFuture]

I'm having trouble figuring out why I am receiving {"guid":null,"status":"pending","error":"Email can't be blank"} after I attempt to create a user. Even though, all of the input fields are correct. I cannot get past this point. My server log information is below. Can you help me, please?

It may be an issue with the Background Worker. I see that the user has been created in my Rails Console, but the process fails over the GUID and default Email. Also, the role is nil, when it's supposed to be user by default.
#<User id: 2, email: "[email protected]", username: "TestDoctor100", created_at: "2017-03-03 02:33:10", updated_at: "2017-03-03 02:33:10", time_zone: nil, role: nil, plan_id: 2, full_name: "David Wright">]>
