Change onClick in your button to <button onClick={e => onUpClick()} ... becouse <button onClick={onUpClick} ..> triggers once the component mount and then it will call toUpperCase() where the text is undefined
Or you could just in your useState do this useState("") set an initial value to it insted of undefined
