MDXTag Error: "components is not defined"

[colshacol]

Bug Report

Describe the bug

When visiting my local docz instance, I am met with the error components is not defined upon navigating (clicking on a sidebar link) to a specific component's view.

I am not quite sure what causes the bug. It seems as though my mdx files are compile to be <MDXTag> components, which accepts a prop components, but the identifier provided doesn't seem to exist in the file. 🤷‍♂️

To Reproduce

Clone, cd packages/core, npm i, npm run docz:dev.
https://github.com/colshacol/g2-ops-component-library
branch: "v1"
Working directly from the packages/core directory.

Expected behavior

I expect docz to show me the mdx documentation I have written for the specific component.

Environment

macOS High Sierra 10.13.6
node v11.1.0 / v10.8.0
npm v6.2.0 / v6.4.1

// doczrc.js
import { css } from 'docz-plugin-css'

export default {
  src: './src/new_components',
  plugins: [
    css({
      preprocessor: 'postcss',
      cssmodules: false,
      loaderOpts: {
        plugins: [],
      },
    }),
  ],
}

"docz": "^0.12.12",
"docz-plugin-css": "^0.11.0",

(Same error with 0.12.12, 0.12.11, 0.12.10, and 0.12.9.)

Note: Before making this issue, I had cleared my yarn cache, npm cache, deleted and re-installed dependencies many times.

I just gave it a go with yarn, and it seems that it did better, but still fell down. Now the error is props is not defined. Sill in the same place, though.

[colshacol]

HelloWorld seems to be working fine now, though... 🤔

Same error with the latest version of docz (0.12.12)

props is not defined

I'm getting the same error whenever I use the <Playground /> component.

[danielbayerlein]

@pedronauck Looks like a critical bug in the current version.

[idrakimuhamad]

I'm not getting the same error as the OP, but definitely getting the @danielbayerlein getting. The usage of Playground will always throw an error props is not defined

[robertpenner]

Also getting props is not defined when I use <Playground>.
Looking at the line where the error is thrown:

<Playground __codesandbox={`undefined`} __position={1} __code={`<MyComponent />`} __scope={{props,MyComponent}}>

It seems props should be this.props, judging by its position in the MDXContent component.

[robertpenner]

I think this was the diff responsible (2 days ago in mdx-js):

mdx-js/mdx@c9c2b32#diff-b327bc77915c976f12c6d2efb717f068R112

Looks like in the refactoring to a class component, in the render method this.props should have replaced props.
(FWIW that code is in a double-nested template literal; good luck linting that.)

same error with props is not defined

[danielbayerlein]

OK, it's a issue in mdx-js, see mdx-js/mdx#324

[johno]

Apologies for this issue, for the time being I recommend pinning @mdx-js/mdx@0.16.0, we'll have it fixed in MDX core tomorrow.

[adbayb]

It could be interesting to match packages version exactly to minimize this sort of issue in the future (currently inside docz/packages/docz-core/package.json, there are carret ranges), what do you think ?

[pedronauck]

Sorry guys, just now I saw this issue, I'm working right now to fix it 🙏

[pedronauck]

Fixed, will be released in the next version

[berbecki]

@pedronauck - When?

[danielbayerlein]

@berbecki Once the release is created.

[pedronauck]

Today @berbecki :)

[jasdeepsingh]

Not sure if 0.16.4 contains the fix for this issue - But I just tried that latest version and it doesn't work. Same error. @pedronauck

[pedronauck]

Fixed on v0.12.13 ✅

[pedronauck]

If bug keeps showing up, try to run yarn dev --debug to invalidate cache or re-install yarn stuff

[andrevvalle]

@pedronauck thanks!

[one-aalam]

Today @berbecki :)

Thanks for v0.12.13 @pedronauck Works like a charm!

[enzoferey]

yarn [your-command] --debug works for me. But we use npm at work, so I have tried re-installing things and it's not working (of course I cleaned up the cache). Any idea why could it be ?
