[error]Cannot process MDX file with esbuild

[jialouluos]

v10.0.1 bug？

import remarkGFM from 'remark-gfm';
const { code} = await bundleMDX({
		source: source.replaceAll(/\$.*(?<val>[\>\=\<]+).*\$/gm, `{'$<val>'}`),
		mdxOptions(options) {
			options.remarkPlugins = [
				...(options.remarkPlugins ?? []),
				remarkGFM,
			];
			options.rehypePlugins = [...(options.rehypePlugins ?? [])];
			return options;
		},
	});

show:Cannot process MDX file with esbuild [plugin @mdx-js/esbuild]

version @9 is running properly

I had this same error today.

I'm using Remix and had mdx-bundler inside serverDependenciesToBundle in remix.config.js, which was required for v9.x.

Removing it again fixed the issue.

I.e.:

//remix.config.js
serverDependenciesToBundle: [
  /^mdx-bundler.*/", // remove this entry
],

I removed remark-gfm and it worked, but I need remark-gfm

Does the gfm plugin for mdx-bundler(v10) exist in error handling for backquotes? The gfm plugin for mdx-bundler(v9) handles backquotes correctly

We're using remark-gfm in production as well with no issues - are you using [email protected] and [email protected]?

Here's our full serverDependenciesToBundle - maybe it will work for you 🤞🏻

serverDependenciesToBundle: [
    // MDX:
    /^rehype.*/,
    /^remark.*/,
    /^unified.*/,
    /^unist.*/,
    /^mdast.*/,
    /^micromark.*/,
    "devlop",
    "ccount",
    "markdown-table",
    "zwitch",
    "fault",
    "decode-named-character-reference",
    "longest-streak",
    "character-entities",
  ],

getting this error when trying to using:

• astro (i dont think this part matters)
• remark-shiki-twoslash, or
• remark-shaku-code-annotate

import {bundleMDX} from 'mdx-bundler'
import { readSync } from 'to-vfile'

import remarkShikiTwoslash from 'remark-shiki-twoslash'

const mdxSource = readSync(`src/components/thing.md`)


const result = await bundleMDX({
  source: mdxSource.toString(),
  mdxOptions (options) {
    options.remarkPlugins = [
       [remarkShikiTwoslash, { theme: "dark-plus" }]
    ]
    return options
  }
  
})

const {code, frontmatter} = result

export { code, frontmatter }

I came to this problem when I write the ill mermaid graph code like this

```mermaid
a -> b
```

after a deep look at the mdx-mermaid plugin process logic

I got no error but the undefined empty result of this function.
It occured to me that maybe something wrong with my mermaid code.
After I chagned to the correct code.

```mermaid
graph TD;
    A-->B;
```

Error disappeard
