Problem

When building multiple entries, the imported functions in the generated bundle are undefined.

Webpack@5.101.0 is the last working version; subsequent versions are incorrect.

Reproduce

npm install -g pnpm

git clone https://github.com/ShenHongFei/webpack-bug.git

cd webpack-bug

pnpm install

# Error: flist should exists
node ./build.js && node ./dist/bundle.mjs

# no error: single entry
node ./build.js normal && node ./dist/bundle.mjs

Error
