Regarding package "remark-ping". Cannot set properties of undefined (setting 'ping')

[mambans]

Hello, I'm wondering if anyone else have gotten this problem before? When I'm parsing the my html with "remark-ping" I get the following error "Cannot set properties of undefined (setting 'ping')".

const htmlTtext = <p><span class="mention" data-index="0" data-denotation-char="@" data-id="419" data-value="Robin Persson"><span contenteditable="false"><span class="ql-mention-denotation-char">@</span>Robin Persson</span></span> </p>;

export const htmlToMarkdown = () => {
	const file = remark()
		.use(rehypeParse, { emitParseErrors: true, duplicateAttribute: false })
		.use(rehypeRemark)
		.use(remarkPing, {
			pingUsername: (name) => true,
			userURL: (name) => https://your.website.com/path/to/${name},
		})
		.use(remarkStringify)
		.processSync(htmlText)
		.then((vfile) => {
			console.log("vfile:", vfile);
			return vfile;
		});

	return String(file);
};```

Hello, the version of remark you are using is too recent for our plugins (more like our plugins being too old for the current version of remark). Please see issue #416 , especially my latest message providing the key figures.
