Describe the bug

Error while trying to convert html text to sanity block @sanity/block-tools.

To Reproduce

Steps to reproduce the behavior:

async function convertHtmlToBlocks(html) {
    const slateAst = await htmlToSlateAST(html);
    console.log(slateAst);
    const blog = htmlToBlocks(html, blockContentType, {
        parseHtml: (html) => new JSDOM(html),
            rules: [
            // Special rule for code blocks
            {
                deserialize(el, next, block) {
                    if (el.tagName.toLowerCase() != 'pre') {
                        return undefined
                    }
                    const code = el.children[0]
                    const childNodes =
                        code && code.tagName.toLowerCase() === 'code' ? code.childNodes : el.childNodes
                    let text = ''
                    childNodes.forEach((node) => {
                        text += node.textContent
                    })
                    // Return this as an own block (via block helper function), instead of appending it to a default block's children
                    return block({
                        _type: 'code',
                        language: 'javascript',
                        text: text,
                    })
                },
            },
        ],

    console.log(blog);
    return blog;

                    { title: 'Code', value: 'code' }
                ],
                annotations: [

                        title: 'URL',
                        name: 'link',
                        type: 'object',
                        fields: [
                            {
                                title: 'URL',

                        ]
                    }
                ]
            }
        }
    ]
};

Expected behavior

    throw new Error("'block' type is not defined in this schema (required).");
          ^
