React child cannot be an object - Storybook

Question

I'm creating a storybook for my design system and I'm getting the following error:

Error: Objects are not valid as a React child (found: object with keys {icon, label, content}). If you meant to render a collection of children, use an array instead.

Tabs.stories.tsx

import { Tabs } from './index';
import { Meta, StoryObj } from "@storybook/react"
import { Gear, PaintBrush, PencilSimple } from "phosphor-react";

const items = [
    {
        icon: <PencilSimple size={20} />,
        label: 'Item 1',
        children: <div>Item 1 content</div>
    },
    {
        icon: <Gear size={20} />,
        label: 'Item 2',
        children: <div>Item 2 content</div>
    },
    {
        icon: <PaintBrush size={20} />,
        label: 'Item 3',
        children: <div>Item 3 content</div>
    },

];

export default {
    title: 'Components/Tabs',
    component: Tabs,
    args: {
        children: items,
        type: "default"
    },
} as Meta

export const Default:StoryObj = {

}

TabsProps.types.ts

import { ReactNode } from "react";

interface Tab {
    label?: string;
    icon?: ReactNode,
    content: ReactNode
}

export interface TabsProps {
    type?: "default" | "secondary";
    defaultValue?: string;
    children: Tab[];
}

If you import the component into another file it works perfectly with the same data, for example:

<Tabs defaultValue={'tab-0'} children={items} />

But in Storybook it doesn't work, showing the above error.

I've put the example at this link:

I managed to solve this problem. For some unknown reason, I can't use the word "Child"

in the interface

The problem was solved when I changed from children to items

Before:

import { ReactNode } from "react";

interface Tab {
    label?: string;
    icon?: ReactNode,
    content: ReactNode
}

export interface TabsProps {
    type?: "default" | "secondary";
    defaultValue?: string;
    children: Tab[];
}

after

import { ReactNode } from "react";

interface Tab {
    label?: string;
    icon?: ReactNode,
    content: ReactNode
}

export interface TabsProps {
    type?: "default" | "secondary";
    defaultValue?: string;
    items: Tab[];
}
