RecipeVariantProps gives undefined in unions due to which storybook doesn't render controls

Description

When I use below to export types

type ButtonVariantProps = NonNullable<RecipeVariantProps<typeof buttonRecipe>>;

Output is

type ButtonVariantProps = {
    variant?: "outline" | "solid" | undefined;
    size?: "medium" | "large" | undefined;
    shape?: "rounded" | "pill" | "square" | undefined;
}

and storybook doesn't render controls

But when I pass the types like below

export type ButtonProps = ComponentProps<"button"> & {
  variant?: "outline" | "solid";
  size?: "medium" | "large";
  shape?: "rounded" | "pill" | "square";
};

Storybook renders the controls correctly

I was just following this tutorial

Tried this, didn't work

type WithoutUndefined<T> = {
    [P in keyof T]?: T[P];
};

type ButtonVariantProps = WithoutUndefined<{
    variant: "outline" | "solid";
    size: "medium" | "large";
    shape: "rounded" | "pill" | "square";
}>;
