waterline validation error

[ariutta]

The waterline validation error at the bottom is shown in the terminal when you click the "Get Token" button on the "Test Auth Flows" page http://localhost:3001/test?code=CODE_VALUE in the example. It's coming from this line. Making it not required removes the error, as in this temporary fix, but should it be required?
