Repro steps

ng new testApp2
ng add @angular/pwa --project=testApp2
npm i @angular/service-worker@next --save (to workaround angular/devkit#679 )
ng build --prod

Observed behavior

resulting ngsw.json

{
  "configVersion": 1,
  "index": "/index.html",
  "assetGroups": [
    {
      "name": "app",
      "installMode": "prefetch",
      "updateMode": "prefetch",
      "urls": [],
      "patterns": []
    },
    {
      "name": "assets",
      "installMode": "lazy",
      "updateMode": "prefetch",
      "urls": [],
      "patterns": []
    }
  ],
  "dataGroups": [],
  "hashTable": {}
}

Desired behavior

urls and patterns should be populated by the entries reflecting the assets in dist/testApp2

Mention any other details that might be useful (optional)

This might be connected to the new folder structure - maybe NGSW CLI is still looking for the files in dist folder instead of dist/[projectName]
