I've updated my existing build to 3.6.1 (I have confirmed this version works fine). I have then installed 'faster' and have enabled this in my docusaurus.config.js file.

I have tried the combination of npm run clear, the recommended removal of the modules/lock files and reinstaillation and still get the issue.

I've also tried to 'downgrade' my rspack version as per the recommendations in #10664 (comment), I can see in my package.lock file this is using 1.0.14, however I get the issue either way!

Thanks

Actual behavior

See the description for error codes

Your environment

• Public source code: N/A
• Public site URL: N/A
• Docusaurus version used: 3.6.1
• Environment name and version (e.g. Chrome 89, Node.js 16.4): Node 22, NPM 10.8.2
• Operating system and version (e.g. Ubuntu 20.04.2 LTS): Mac Version 15.0.1

Self-service

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

It is impossible to help you without a repro.

The error message is familiar to me and is very likely related to a custom or third-party Docusaurus plugin that doesn't support Rspack and is using webpack.DefinePlugin instead of currentBundler.instance.DefinePlugin

Please read this to understand what must be done: #10572
