My screen getting blank when i use mdx live editor. #5555

fiqryq · 2021-09-11T15:52:37Z

🐛 Bug Report

Prerequisites

I'm using the latest version of Docusaurus.
I have tried the npm run clear or yarn clear command.
I have tried rm -rf node_modules yarn.lock package-lock.json and re-installing packages.
I have tried creating a repro with https://new.docusaurus.io
I have read the console error message carefully (if applicable)

Description

I try to use MDX using livecodeblock , everything is okay until I try to delete all code on the live editor and when i press delete one more time my screen getting blank and my console give me this code : Nothing was returned from render. This usually means a return statement is missing. Or, to render nothing, return null.

Have you read the Contributing Guidelines on issues?

Yes

Expected behavior

i can delete my code on the live editor.

Actual behavior

console code : Nothing was returned from render. This usually means a return statement is missing. Or, to render nothing, return null.

Could you please provide reproducible code or video? For example, I don't see an error if I delete code from the section on docs website.

ChristopherHButler · 2021-09-11T18:55:41Z

I'm having the same or similar issue. I tried following the instructions at https://docusaurus.io/docs/markdown-features/code-blocks#interactive-code-editor to add a live code editor and when I add the live tag to the meta string my app basically crashes. I have also attached a screenshot with console output. As soon as I remove the live tag everything works fine again.

docusaurus.config.js:

const lightCodeTheme = require('prism-react-renderer/themes/github');
const darkCodeTheme = require('prism-react-renderer/themes/dracula');

@ChristopherHButler I need reproducible repo, could you provide it?

ChristopherHButler · 2021-09-11T19:29:34Z

@lex111 sure thing. Here is my repo: https://github.com/ChristopherHButler/docs.

I do not have my docs in the docs folder. You can find the example of the broken live codeblock under docz > engineering > typescript > 1-basics > 00-introduction.md. I just copied in the example from the docusaurus site at line 11.

Let me know if you need anything else

lex111 · 2021-09-11T21:10:51Z

@ChristopherHButler thanks, but in your case, the problem with React version mismatch (you use v17, but the latest minor version react-live 2.3.0 rewritten on hooks uses v16). yarn can resolve this automatically, but npm you use doesn't.

A workaround would be to downgrade React to v16/run app via yarn instead of npm/add webpack alias. But it would be better if we just use the previous version react-live 2.2.0. I created PR for this #5556.

ChristopherHButler · 2021-09-11T21:38:08Z

Thanks @lex111 I'll downgrade for now and maybe keep an eye out for that PR.

I was discussing with someone on Discord about this as well, it's specific to the case where an invalid React child (e.g. an object like console) is passed to the live scope without being wrapped by a function. Seems this is caused by a bad error boundary

The bug is reproduced on react-live playground https://react-live.netlify.app/, so the issue related with this dependency.
