I don't understand - how are you using our parser to parse markdown?
What config are you using?

Here is the config file: https://github.com/ant-design/ant-design/blob/25788e69a8e8cad8cf9c239493293cf24e1b2176/.eslintrc.js#L23

with markdown plugin

It will probably work if you set this in your .eslintrc.js

parserOptions: {
  ecmaFeatures: {
    jsx: true,
  },
}

Thanks for quick response. Tested, seems still meet same error.

+1, my eslint-mdx breaks due to this, and I've wasted a whole afternoon to figure out this is a BREAKING CHANGE from @typescript-eslint/parser...

Again, as per #1124 - it is a bug, unintentionally introduced.

I understand you're frustrated, but please understand that ESLint is a very complex, and extensive environment.

ESLint itself calls into our parser in a certain format.
There are parsers which call into our parser in a different format.
And apparently, there are preprocessors which call into our parser in another different format.

TBH, I didn't even know that this particular use case existed before today.

@bradzacher Sorry for my impatient, I was just too upset at that time.

I personally wrote an eslint parser/plugin for mdx either, so I do understand the complexity of eslint. There are so many edge cases.
