Lexical Editor: Link and AutoLink not converting to markdown with lexical $convertToMarkdownString

[shawnvogt]

Link to reproduction

https://github.com/TMRRWinc/PayloadLexicalLinkConvertToMarkdownIssue

Describe the Bug

When using the $convertToMarkdownString_function from @lexical/markdown, the Link and AutoLink nodes do not correctly convert.

expected output [link](https://payloadcms.com) actual output link

if the Link and AutoLink nodes from @lexical/link are subbed into the headless editor nodes, the the actual output changes to [link](undefined)

To Reproduce

run the "local API example" test in test/_community/int.spec.ts of the linked reproduction

A richtext field with lexical editor was added to the posts collection. The richtext field has a field hook to convert the lexical state to markdown and attach it to context. A collection AfterChangeHook adds the markdown value to the returned document to make the markdown value available to test against.

OR (follow the steps from the docs and then try to convert a link)

Lexical => Markdown

Export content from the Lexical editor into Markdown format using these steps:

1. Import your current editor state into the headless editor.
2. Convert and fetch the resulting markdown string.

Here's the code for it:

import { $convertToMarkdownString } from '@lexical/markdown'
import { sanitizeEditorConfig } from '@payloadcms/richtext-lexical'
import type { SerializedEditorState } from "lexical"

const yourSanitizedEditorConfig = sanitizeEditorConfig(yourEditorConfig) // <= your editor config here
const yourEditorState: SerializedEditorState // <= your current editor state here

// Import editor state into your headless editor
try {
  headlessEditor.setEditorState(headlessEditor.parseEditorState(yourEditorState)) // This should commit the editor state immediately
} catch (e) {
  logger.error({ err: e }, 'ERROR parsing editor state')
}

// Export to markdown
let markdown: string
headlessEditor.getEditorState().read(() => {
  markdown = $convertToMarkdownString(yourSanitizedEditorConfig?.features?.markdownTransformers)
})
