説明

I know @1egoman most likely won't update this project anymore (debundle v2), but if someone can help then please:

I installed the project, changed directory to it and ran `npm install` it installed some packages and once i tested it with this command: `node src/index.js bundle.js` it gave me this error (full log):
```
PS D:\Downloads\debundle-2\debundle-2> node src/index.js bundle.js

Node.js v20.16.0
```
which I think is releated to referencer.js and not to this project, so can anyone help?

調査の方向性

The error occurs in escope's referencer.js when processing a webpack bundle. Start by examining src/subcomponents/WebpackBootstrap.js line 9 and src/subcomponents/Bundle.js lines 247 and 78 to see how the bundle is parsed. Check the bundle.js input file for any unusual function declarations that might cause escope to fail. Look into the escope library version and its compatibility with Node v20.16.0. Running the failing command with debug logs might reveal the problematic AST node.
