JS ERROR Error: not implemented

Hello there,

i'm getting hard times getting a pretty simple code to work in NativeScript 2.1.1 - Angular 2 2.0.0-rc3:

let headers = new Headers();
        headers.append("Content-Type", "application/text");

        this._http.get(
            "https://v-ticket.com.ua/api/Login/__pass=c84a0f0b2bb8e1c6bfb565c92a4ad4a9",
            { headers: headers }
        )
            .subscribe(
                res => console.log(res.json()),
                err => console.log(err.json())
            );

After the launch the app crashes with the following log:

To me it looks like the xhr_backend.js module it trying to call getCookie() on an getDom() which is null.

What am I doing wrong?

Copied from original issue: NativeScript/NativeScript#2452

I believe this is the same as #305.
Long story short:

• If you are using 0.2.0(current latest) - you should provide the HTTP_PROVIDERS in the app bootstrap function. If you do it directly in the component providers array - you get the error.
• In vNext you will just have to provide NS_HTTP_PROVIDERS - no matter where.

You're right – it's the same issue.

Thanks, for pointing that out. Resolved.

[jtemerson]

So what is the implementation of this? I am new to AngularJS and Nativescript. Where is the Bootstrap function and how do provide HTTP_PROVIDERS in the function?
