Warning in form

[Servesh Chaturvedi]

I'm facing this warning when changing the username field:
Warning: A component is changing an uncontrolled input to be controlled. This is likely caused by the value changing from undefined to a defined value, which should not happen. Decide between using a controlled or uncontrolled input element for the lifetime of the component.
Other fields are working as expected.
Also getting duplicate of issue 1456.
