uid is blank upon basic rails 5 api setup, user registration

Setting up a fresh rails 5 in api-mode

Following along this guide and have hit a snag: https://github.com/dnasseri/rails5-api-guide (the part where the first curl command is shown)

Trying to perform a very basic user registration under test conditions. Sending post request from my client and is hitting the correct route.

Each record is not having a 'uid' field generated. The first record saves fine because it falls to default as "". It is required to be unique so two ""'s are a no go.

Why is this field even needed since it is a user record and the id field is there? Why clue as to why uid is not being generated?

Thanks!

Kind of inconclusive whether Rails 5 or API are compatible:
#458

Could you try running the test suite against your setup?
