React-styleguidist: Updating from 7.3.10 to 7.3.11 throws ReferenceError: returntrue is not defined

[philiiiiiipp]

Current behavior

After updating from 7.3.10 to 7.3.11 I see this error when going to the our styleguidist website.

ReferenceError: returntrue is not defined
    in xt (created by ve)
    in footer (created by ve)
    in main (created by ve)
    in div (created by ve)
    in ve (created by Styled(ve))
    in Styled(ve) (created by t)
    in t
This may be due to an error in a component you are overriding, or a bug in React Styleguidist.

If you believe this is a bug, please submit an issue.

the console is also full of them:

I double verified, it works with 7.3.10 but not with 7.3.11.

To reproduce

I am not sure what triggered this other than the update. The examples seem to work fine.

We are using:

Let me know what other information I can provide.

Expected behavior

Should show the website.

This only appears to be an issue with [email protected]. Using [email protected] seems to work.

Pinning webpack back to 4.21.0 also worked for me. (Also had to pin buble to 0.19.4...currently 0.19.5 is causing a different issue)

[eemeli]

Pinning webpack isn't working for me. For a proper fix (which works at least with react-styleguidist 8.0.0), you need to pin its markdown-to-jxs dependency to 6.7.4 or earlier, as its 6.8 release added an (undocumented!) output minification step that's causing this issue.

The upstream issue probablyup/markdown-to-jsx#224 was closed, probably incorrectly. Not really sure what's the original source of the problem though.

[probablyup]

Hi folks, please try markdown-to-jsx 6.8.2

[yorthehunter]

Pinning markdown-to-jsx to 6.8.2 worked for me.

FYI, here's what it looks like in my package.json (I'm using Yarn):

  "resolutions": {
    "markdown-to-jsx": "6.8.2"
  },

[probablyup]

@sapegin this can be closed now - definitely fixed with 6.8.2
