Cannot read properties of undefined (reading 'values')

See original GitHub issue

Describe the bug I am using Storybook and React on my project and I am having an error when I tried to see the Docs of my component: image

The weird thing is that the component looks great, I only have this issue with Docs. image

To Reproduce This is my code. Breadcrumb.tsx:

import { Grid } from "@mui/material";
import { styled } from "@mui/material/styles";
import { B500 } from "../colors/Colors";
import { Item } from "./components/Item";
import { createGenerateClassName, StylesProvider } from "@mui/styles";

export interface IBreadcrumbProps {
  /** The icon that appears at the start of the Breadcrumb. */
  icon: JSX.Element;
  children: any;
  /** The extra CSS styles of the component. */
  style?: Object;
}

const StyledGrid = styled(Grid)({
  "& > svg, & > svg > g > use": {
    fill: `#${B500}`,
    height: "16px",
    width: "16px",
  },
});

const breadcrumb = createGenerateClassName({
  seed: "breadcrumb",
});

export const Breadcrumb = ({ icon, children, style }: IBreadcrumbProps) => {
  return (
    <StylesProvider generateClassName={breadcrumb}>
      <StyledGrid container alignItems="center" style={style}>
        {icon}
        {children}
      </StyledGrid>
    </StylesProvider>
  );
};

Breadcrumb.Item = Item;

Breadcrumb.stories.tsx:

import { Breadcrumb } from "./Breadcrumb";
import { AssessmentIcon } from "../icons/Icons";

export default {
  title: "Breadcrumb",
  component: Breadcrumb,
};

export const Default = (args) => {
  return (
    <Breadcrumb {...args} icon={<AssessmentIcon />}>
      <Breadcrumb.Item
        label="Label number one"
        onClick={() => console.log("Click on the first label.")}
      />
      <Breadcrumb.Item label="Label number two" />
    </Breadcrumb>
  );
};

Default.argTypes = {
  icon: { control: { disable: true } },
};
