Error in webpack debundler using the default config settings

I've tried this debundler package (https://www.npmjs.com/package/debundle) to test it but it failed using the simple config with a test file. I tried to set entry point to 0 but it still gave me the below error: Error: Don't have enough information to expand bundle into named files.

with Browserify set as the bundler it gives a different error, config.entryPoint = ast.body[0].expression.arguments2.elements[0].value;

{
  "type": "webpack",
  "entryPoint": 1,
  "knownPaths": {}
}

error using webpack as debundler

error with browserify as debundler
