Should be related to https://github.com/mdx-js/eslint-mdx/issues/384#issuecomment-1110737802, waiting for micromark/micromark-extension-mdx-expression#4.

micromark is released!

[JounQin]

I created #393 to make sure, after upgrading micromark-util-events-to-acorn, it works as expected.

@B2o5T Please upgrade it by yourself by deleting yarn.lock, etc.

[dimaMachina]

@JounQin upgraded but the issue was not solved even on the latest micromark-util-events-to-acorn@1.1.0

info from yarn.lock

micromark-util-events-to-acorn@^1.0.0:
  version "1.1.0"
  resolved "https://registry.yarnpkg.com/micromark-util-events-to-acorn/-/micromark-util-events-to-acorn-1.1.0.tgz#9891638e201c266484d0af7cd2505d208f73db9d"

[JounQin]

Can you please provide a runnable reproduction?

[JounQin]

Oh, should also be related to https://github.com/mdx-js/eslint-mdx/issues/384#issuecomment-1123625050

The jsx tokens are not available for now.

[JounQin]

@B2o5T Besides, the two rules are disabled for mdx content in the recommended config at https://github.com/mdx-js/eslint-mdx/blob/master/packages/eslint-plugin-mdx/src/configs/overrides.ts#L23-L35, that's why I can't reproduce it at #393

Of course, the missing tokens are still a problem, but that would be another issue, so close this one for now.

---

Edit, Just notice you didn't use plugin:mdx/recommended at all.

[JounQin]

Close because duplicate of #384

@B2o5T

Please try:

# yarn 1
yarn add https://pkg.csb.dev/mdx-js/eslint-mdx/commit/cc2cd6c2/eslint-mdx https://pkg.csb.dev/mdx-js/eslint-mdx/commit/cc2cd6c2/eslint-plugin-mdx
# yarn 2, 3
yarn add eslint-mdx@https://pkg.csb.dev/mdx-js/eslint-mdx/commit/cc2cd6c2/eslint-mdx/_pkg.tgz eslint-plugin-mdx@https://pkg.csb.dev/mdx-js/eslint-mdx/commit/cc2cd6c2/eslint-plugin-mdx/_pkg.tgz
# npm
npm i https://pkg.csb.dev/mdx-js/eslint-mdx/commit/cc2cd6c2/eslint-mdx https://pkg.csb.dev/mdx-js/eslint-mdx/commit/cc2cd6c2/eslint-plugin-mdx

It should just work now:

https://github.com/mdx-js/eslint-mdx/pull/394/files#diff-7dc63d54389fc5b805a5cebe74578027e4837d2eb08085555c7792fad8da8552R397
