Error: Cannot handle unknown node delete

[adaboese]

I am trying to create a plugin that highlights text between ~...~ and I am getting this error:

Error: Cannot handle unknown node delete

Here is the code:

/* eslint-disable unicorn/prevent-abbreviations */

import { markRule } from '@milkdown/prose';
import { $inputRule, $markAttr, $markSchema } from '@milkdown/utils';

export const strikethroughAttr = $markAttr('strike_through');

export const strikethroughSchema = $markSchema('strike_through', (context) => ({
  parseDOM: [
    { tag: 'del' },
    {
      getAttrs: (value) => (value === 'line-through') as false,
      style: 'text-decoration',
    },
  ],
  parseMarkdown: {
    match: (node) => node.type === 'delete',
    runner: (state, node, markType) => {
      state.openMark(markType);
      state.next(node.children);
      state.closeMark(markType);
    },
  },
  toDOM: (mark) => ['del', context.get(strikethroughAttr.key)(mark)],
  toMarkdown: {
    match: (mark) => mark.type.name === 'strike_through',
    runner: (state, mark) => {
      state.withMark(mark, 'delete');
    },
  },
}));

/// Input rule to create the strikethrough mark.
const strikethroughInputRule = $inputRule((context) => {
  return markRule(/~([^~]+)~$/u, strikethroughSchema.type(context));
});

export const highlight = [
  strikethroughInputRule,
  strikethroughSchema,
  strikethroughAttr,
].flat();

any guidance what I am missing?

@adaboese Have you figured it out? I have exact problem :/

The problem of this is caused by that you don't have that kind of node in remark AST. You'll need a remark plugin to complete the feature.
