[windily-cloud]

I really love this project so much. This is awesome work!!!

But i have some issue：

Cannot read properties of undefined (reading 'data')

I try to log, wikilink is undefined:

Then i go to see the exit function：

In the remark-wiki-link package, I found that my code were giving me errors, and after checking that wikilink was returning undefined, I returned the node, and it worked. I don't know if this is a problem, or if something is wrong. I'm not sure if this is a problem or what's wrong.

Thx for any reply!

This issue might be caused by the version 2.0 of mdast-util-from-markdown. https://github.com/syntax-tree/mdast-util-from-markdown/commit/18f4bb0f1b720fd30f1c3a7b11e1fac90aa6903f

I also started experiencing this issue in my Astro site after upgrading from Astro 3 -> 4. According to their docs, it looks like they upgraded the following packages:

• unified
• remark
• rehype

Potentially this is an error with this package not being compatible with the latest version of one or more of these dependencies?

Since this.exit no longer has a return value, I made the following modifications in my self-maintained version. Currently, it works in my use case, but it is unclear if there are any other issues. Can someone raise a PR to fix this issue? fromMarkdown.ts#L76C3-L76C3

const wikiLink = top(this.stack)
const {
    data: {isEmbed, target, alias},
} = wikiLink;
this.exit(token);

I am also experiencing this issue! I'll try out @yuhangch's solution against my use case, but I'm also unsure if I will be able to to put up a PR.

Add @yuhangch 's modification to exitWikiLink function in remark-wiki-link/dist/index.js works! 👍
