I’m trying to upload an app to Ionic View unsuccessfully.  
`Ionic link` worked well but when i ran `ionic upload` I got an error.  
My app is using firebase.  
App is working fine on an emulator.

ionic info -

```auto
cli packages:

    @ionic/cli-plugin-ionic-angular : 1.4.0 (e:\Ionic\Conv_blank\node_modules\@ionic\cli-plugin-ionic-angular)
    @ionic/cli-utils : 1.6.0 (e:\Ionic\Conv_blank\node_modules\@ionic\cli-utils)
    ionic (Ionic CLI) : 3.6.0 (e:\Ionic\Conv_blank\node_modules\ionic)

local packages:

    @ionic/app-scripts : 2.1.3
    Ionic Framework : ionic-angular 3.6.0

System:

    Node : v6.11.1
    OS : Windows 10
    npm : 3.10.10

```

This is the output I’m getting -

Please edit your post, it is not very readable at the moment.  
Use the `</>` button above the input field to format your code, command line output or error message (select the text first, then click the button or wrap it in ````` manually). Check the preview if it looks better. This will make sure your text is readable and if it recognizes the programming language it also automatically adds code syntax highlighting. Thanks.

Post your `ionic info` output please.  
Post the whole command your are running with all output it generates.

I have the sam issue.

`Ionic serve` runs without Problems.

```auto
ionic build

```

runs with the same error.

```auto

Please post your complete error.

Yours has nothing to do with `ionic upload` or the Ionic View app?

gyjoules already postet the complete Output.

I found a solution that worked for me.

`npm install promise-polyfill --save-exact`

Solved it for local build.

To solve this for remote build (ionic pro) I add

`"promise-polyfill": "^6.0.2"`

to the package.json dependencies.

I’m baffled as to why promise-polyfill should be needed anywhere today.

It may not be, but a firebase.Promise isn’t the same as a regular Promise, so I’m willing to believe that it’s possible to create an issue. Firebase connects its promise to a Thenable interface. Casting to a standard Promise is usually fine in my experience, but maybe the OP is doing something special.

</div>

But (as I understand it) promise-polyfill is only needed if you are operating in a runtime environment that lacks proper `Promise`s, which shouldn’t be true of anything an Ionic app is running in, or of any node environment that build tools are.

Maybe the Firebase code is old? I’ve looked at some of the AngularFire code, but never at the Firebase code. I’m not even sure how much is open source.

Judging from [this](https://github.com/firebase/firebase-js-sdk/search?utf8=%E2%9C%93&q=promise-polyfill&type=), it would never come into play in a modern environment.

I don’t yet understand what I’m looking at, sorry. Should I infer that it’s required for build but never used?

It’s a search across the code base showing that the only place it would ever take effect is if there is no `Promise` in the global scope (which should never happen today), so it’s effectively an obsolete dependency.

@aaronsterling @rapropos The problem is not that the code actually needs it, but that webpack doesn’t know that it does _not_ need it. It just sees the `require` and tries to get the code, which it can’t find as it isn’t installed (as it isn’t really needed).
