Warning: A component is changing an uncontrolled input of type text to be controlled.
Input elements should not switch from uncontrolled to controlled (or vice versa).
Decide between using a controlled or uncontrolled input element for the lifetime of the component.
More info: https://fb.me/react-controlled-components

Warning: `value` prop on `input` should not be null.
Consider using an empty string to clear the component or `undefined` for uncontrolled components.
