plugin-debug can't be compatible with React 19 due to dependency on old react-json-view-lite

Have you read the Contributing Guidelines on issues?

• I have read the Contributing Guidelines on issues.

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

react-json-view-lite used in plugin-debug has not been compatible with React 19 in its peerDependencies.
To make matter worse plugin-debug does not use the latest version of it.

• Support for react 19 AnyRoad/react-json-view-lite#34

Reproducible demo

1. https://docusaurus.new/codesandbox-ts
2. Remove node_modules
3. yarn install

Steps to reproduce

1. Update React (react, react-dom, and @types/react) to 19
2. npm, yarn, or pnpm install if not done

Expected behavior

No warnings or errors

Actual behavior

Warning (or error) complaining about unmet peer dependencies on React

e.g. Yarn (Official CodeSandBox):

warning "@docusaurus/preset-classic > @docusaurus/plugin-debug > react-json-view-lite@1.5.0" has incorrect peer dependency "react@^16.13.1 || ^17.0.0 || ^18.0.0".

Your environment

• Public source code:
• Public site URL:
• Docusaurus version used: 3.7.0
• Environment name and version (e.g. Chrome 89, Node.js 16.4): Node 22.12
• Operating system and version (e.g. Ubuntu 20.04.2 LTS): Windows 11

Self-service

• I'd be willing to fix this bug myself.

Thanks, I'll upgrade to the latest asam and also opened a PR there AnyRoad/react-json-view-lite#43

[tats-u]

Thank you for your quick response.

👍

I'll close this for now but we'll do something if the lib doesn't publish anything in the near future, eventually publish a fork if needed

Could you make a patch release out of this? This bug virtually renders the React 19 compatibility promise highlighted in the announcement of the Docusaurus 3.7.0 release unusable.

Has just been released:

https://github.com/AnyRoad/react-json-view-lite/releases/tag/2.2.0

[tats-u]

The last task is to release Docusaurus 3.7.1
(DocSearch is still incompatible but is not used by all sites)

[tats-u]

Docsearch is now compatible with React 19 in the latest version. We need to bump it. (semver compatible though)
