polymer build --js-minify flag breaks iron-ajax for Polymer 1

[soumyart]

Description

Iron-ajax is not working after minifying the code using latest cli for Polymer 1 application. Once removed the --js-minify flag ajax worked as expected.

polymer.josn

  "fragments": [
    "src/my-view1.html",
    "src/my-view2.html",
    "src/my-view3.html",
    "src/my-view404.html"
  ],
  "sources": [
    "src/**/*",
    "images/**/*",
    "JSONs/*",
    "bower.json"
  ],
  "extraDependencies": [
    "manifest.json",
    "bower_components/webcomponentsjs/webcomponents-lite.min.js"
  ]
}

Iron ajax is not firing.

698 changes didn't fixed the issue for me

super({presets: [babiliPreset(null, {'unsafe': {'simplifyComparisons': false }})]});

Is there anything else that needs to be changed?

[christophe-g]

Sorry to ask, but did you re-build polymer-cli after the change ? It does work for me with similar config. C.

[doughaase]

Sorry, forgot about that.

I've downloaded the updated repo and tried npm run build

Output was an error:
