Custom icons: Typescript and ESLint errors in Next.js 14

[IonelLupu]

Describe the bug

Copy paste a custom icon example from the readme page into your Nextjs 14 project:

import { forwardRef, ReactElement } from "react";
import { Icon, IconBase, IconWeight } from "@phosphor-icons/react";

const weights = new Map<IconWeight, ReactElement>([
  ["thin", <path d="..." />],
  ["light", <path d="..." />],
  ["regular", <path d="..." />],
  ["bold", <path d="..." />],
  ["fill", <path d="..." />],
  [
    "duotone",
    <>
      <path d="..." opacity="0.2" />
      <path d="..." />
    </>,
  ],
]);

const CustomIcon: Icon = forwardRef((props, ref) => (
  <IconBase ref={ref} {...props} weights={weights} />
));

CustomIcon.displayName = "CustomIcon";

export default CustomIcon;

Getting a Typescript error:

TS2322: Type
ForwardRefExoticComponent<Omit<IconProps, 'ref'> & RefAttributes<SVGSVGElement>>
is not assignable to type Icon
Types of property defaultProps are incompatible.
....

Expected behavior

To not get any errors

Additional notes

This error wasn't there prior to updating Nextjs (and related packages) from Nextjs 13 to Nextjs 14

Looks like as Icon fixes the issue:

const CustomIcon: Icon = forwardRef((props, ref) => (
    <IconBase ref={ref} {...props} weights={weights} />
)) as Icon;

I think the docs need to be updated to reflect it
