How can I fix this?

Here's a code

import Head from "next/head";
import { Container, Row, Col, Card, Spinner } from "react-bootstrap";
import { VectorMap } from "@react-jvectormap/core";
import { esMill } from "@react-jvectormap/spain";
import styles from "../styles/Home.module.css";

const Home = () => {
    return (
      <div>
        <Head>
          <title>Map View</title>
          <meta name="description" content="Generated by create next app" />
          <link rel="icon" href="/favicon.ico" />
        </Head>

        <div className={styles.wrapper}>
          <div className="py-5">
            <Container className="py-5">
              <Row sm={1}>
                <Col className="my-3">
                  <Card className={`${styles.card} h-100`}>
                    <Card.Body>
                      <h5>Map</h5>
                      <div>
                        <VectorMap map={esMill} />
                      </div>
                    </Card.Body>
                  </Card>
                </Col>
              </Row>
            </Container>
          </div>
        </div>
      </div>
    );
};

export default Home;

You need to dynamically import VectorMap as it is unable to be rendered server side. Here is how I have it running in a project.

import dynamic from 'next/dynamic';
import worldMill from '@react-jvectormap/world/worldMill.json';

const VectorMap = dynamic(
  // @ts-ignore
  () => import("@react-jvectormap/core").then((m) => m.VectorMap),
  { ssr: false, }
);

export const Jmap = ({ series }: any) => {
  return (
    <div>
      <VectorMap
        map={worldMill}
        series={series}
      />
    </div>
  );
}

Thank you! Heads up for other devs: I have imported worldMill by destructuring command { worldMill } ... but this threw another error. You should import just as written above to get it to work
