Eel unable to parse arrow functions when running after npm run build

[honkwansin]

Eel version 0.16.0

Describe the bug Eel cannot parse arrow functions such as: const funcName = (funcParam) => {console.log(funcParam)} window.eel.expose(funcName, 'funcName') after running npm run build and then python main.py. but when rephrased to function funcName(funcParam) { console.log(funcParam)} window.eel.expose(funcName, 'funcName') everything works fine.

To Reproduce

1. Use CRA template (example/07)
2. write an arrow function
3. call it from python
4. npm run build
5. python YOUR_MAIN_FILE.py

Expected behavior both function styles should be parsed all the same
