Stats parsing is broken when using "all: true" and Webpack 5

[slavafomin]

Hello!

Thank you for this great tool!

Issue description

However, I've encountered a situation when stats file parsing is broken when using the following stats configuration:

const statsConfig = {
  all: true,
  context: projectPath,
  source: false,
}

and Webpack 5.22.0.

Technical info

The problem is in the assetHasModule function:

function assetHasModule(statAsset, statModule) {
  // Checking if this module is the part of asset chunks
  return statModule.chunks.some(moduleChunk => statAsset.chunks.includes(moduleChunk));
}

It raises the following error:

TypeError: Cannot read property 'some' of undefined

because statModule.chunks is undefined in this case.

In my example the module stat object has the following structure:

{
  "type": "modules by path",
  "name": "…node_modules/.pnpm/core-js@3.8.3/node_modules/core-js/internals/*.js",
  "children": [
    // A big list of modules here
  ],
  "size": 22868,
  "sizes": {
    "javascript": 22868
  }
}

---

Also, when I change the stats config to use "verbose" preset, the error goes away, but when I view the bundle layout in "parsed" format, it only renders the entry point module. I think something is broken on a more fundamental level.

---

I've uploaded the obfuscated version of my stats.json file generated with the latest version of the Webpack using "verbose" preset.

Thanks for the issue! This might be a regression stemming from #395 where the assetHasModule previously used lodash's _.some method, which likely works better when the value given in is undefined.

Should be fixed in v4.4.1, thanks to @deanshub via #433. Let us know if the fix works for you ☺️
