using core-js with Angular 2

[rolandjitsu]

I was trying to compile my project directly to ES6 and use core-js for shims (they seem to cover a lot more than es6-shim), but it looks like I get a an error:

TypeError: Cannot convert undefined or null to object
angular2.min.js:26Uncaught TypeError: Cannot read property 'getOptional' of undefinedu @ angular2.min.js:26t._initApp @ angular2.min.js:26t.application @ angular2.min.js:26n @ angular2.min.js:26(anonymous function) @ bootstrap.ts:37(anonymous function) @ bootstrap.ts:37U @ system.src.js:4597c.execute @ system.src.js:4597i @ system.src.js:4597n @ system.src.js:4597execute @ system.src.js:4597y @ system.src.js:4597w @ system.src.js:4597p @ system.src.js:4597h @ system.src.js:4597(anonymous function) @ system.src.js:4597n.run @ angular2.min.js:1(anonymous function) @ angular2.min.js:1I @ angular2.min.js:1A @ angular2.min.js:1R @ angular2.min.js:1(anonymous function) @ angular2.min.js:1n.run @ angular2.min.js:1(anonymous function) @ angular2.min.js:1h @ angular2.min.js:1h @ core.js:3055(anonymous function) @ core.js:3066e @ core.js:3310

Not sure why though. If I compile to ES5, it works perfectly fine.

Here is my tsconfig.json for reference:

{
    "compilerOptions": {
        "emitDecoratorMetadata": true,
        "experimentalDecorators": true,
        "module": "commonjs",
        "moduleResolution": "node",
        "noImplicitAny": false,
        "sourceMap": true,
        "target": "es5"
    }
}

Try switching your script from angular2.min.js to angular2.dev.js and you should get more information about the problem. Also check your typescript compiler errors.

Looks like this is related to the other open issue #5755, referencing for convenience.
