Assessment

Difficulty: 4/5
Estimated time: 3-5 days
Newbie friendliness: 45/100

Issue type: Bug
Clarity: Mostly clear
Activity status: Stale
Tech stack: node.js, typescript
Domain: backend

Research direction

Start with the failing config/plugin.ts entry shown in the log, then read @eggjs/core/src/utils/index.ts and @eggjs/core/src/loader/egg_loader.ts around loadFile and readPluginConfigs. Reproduce the failure with npm run dev using the reported Node v20 setup. Done means Egg 4 can load the reported ESM configuration without the exports error.
