Details

I was finally able to create a reproducible env for the bug that we experience during the migration of our webpack to rspack setup. The error that is thrown when SSR-ing the react content from the server with:

TypeError: Cannot read properties of undefined (reading 'ReactCurrentDispatcher')

We have a reproducible env where we bundle the application in 3 different flavours and our setup works on 2 of the 3 modes:

• webpack + babel ✅
• webpack + swc-loader ✅
• rspack + buildin swc-loader 🔴

Reproduce Steps

Steps to reproduce

I've provided a minimal reproducible env, to test it out:

Clone: Reproducible error project

Execute npm ci

Run: npm run webpack:swc:dev:server

Hit route: http://localhost:3001/ => works ✅

Run: npm run webpack:babel:dev:server

Hit route: http://localhost:3001/ => works ✅

*Run: npm run rspack:dev:server

Hit route: http://localhost:3001/ => will fail with TypeError: Cannot read properties of undefined (reading 'ReactCurrentDispatcher')🔴
