React Hook Form's register function does not work when using custom components-CodePudding

I'm refactoring some code in my app and I noticed that when I moved my input element to be its own reusable component, hook-form's register function stopped working. This can be fixed if you use the plain input element, but I would like to use my own component. Here's a stack blitz with a reproducible example: https://stackblitz.com/edit/react-ts-9bafks?file=App.tsx

If you check what register('text') actually gives you console.log(register("text")) you will see that there is a ref. You have to make your custom inputs to forward that ref.

const TextInput: FC<Props> = React.forwardRef(({ error, ...props }, ref) => {
  return (
    <div>
      <p> {error} </p>
      <input {...props} ref={ref}/>
    </div>
  );
});
