Within my custom block plugin, I am using create-block to generate my block environment for block editing. Within my `src/edit.js file I have the following setup…

import { __ } from 'wordpress user/i18n';
import {
    useBlockProps,
    Fragment,
    RichText,
    BlockControls,
} from 'wordpress user/block-editor';
import './editor.scss';

export default function Edit( { attributes, setAttributes } ) {
    const { text } = attributes;

    // additional options for our RichText component - https://github.com/WordPress/gutenberg/blob/HEAD/packages/block-editor/src/components/rich-text/README.md
    return (
        <Fragment>
            <BlockControls controls={[{
                title: "Button 1",
                icon: "admin-generic",
                onClick : () => console.log("Button 1 clicked!"),
            },]} />
            <RichText
                { ...useBlockProps() }
                onChange={ ( value ) => setAttributes( { text: value } ) }
                value={ text }
                placeholder={ __( 'My chocolate placeholder', 'chocolate' ) }
                tagName="h4"
                allowedFormats={ 'core/bold' }
            />
        </Fragment>
    );
}

…But when I run npm start, and go to my edit page, I get the following error in the console…

Block validation: Block validation failed for `course-blocks/chocolate` ( ....}

What is the recommended approach to using fragments with create-block?
