Uncaught RangeError: Duplicate use of selection JSON ID cell

[tech-milky]

I follow this example:

import ReactDom from 'react-dom';
import React from "react";
import {SmartBlock} from "smartblock";

let html = document.currentScript.getAttribute('data-html');
let element = document.currentScript.getAttribute('data-element');
const extensions = [
    new Heading1()
];

var app = document.getElementById("hello");

ReactDom.render(
    <SmartBlock
        extensions={extensions}
        html={`<ul>
      <li>list item 1</li>
      <li>list item 2</li>
    </ul>`}
        onChange={({ json, html }) => { console.log(json, html);}}
    />, app);

and I have this error
