Description
Issue Description
I have a NativeScript with angular project. The backend is a rest api written in .NET CORE. I'm trying to make a HTTP call fom the nativescript frontend following the post method under 'request' section as described in the link: https://docs.nativescript.org/http.html#request
Whenever I make a call, I get error -
JS: ERROR Error: Uncaught (in promise): Error: java.io.IOException: unexpected end of stream on com.android.okhttp.Address@1d8e59ae
JS: Error: java.io.IOException: unexpected end of stream on com.android.okhttp.Address@1d8e59ae
JS: at onRequestComplete (file: src\webpack:\ns-blendedsupport-mvp\node_modules@nativescript\core\http\http-request\index.android.js:49:33)
JS: at Object.onComplete (file: src\webpack:\ns-blendedsupport-mvp\node_modules@nativescript\core\http\http-request\index.android.js:38:12)

let apiURL = "http://10.0.2.2:4001/api/Login/Login";
let data = JSON.stringify(this.loginModelData);
Http.request({

}
else
{

}
}

Research direction
Start with the request in authenticationservice.ts and compare it with the Android completion path in @nativescript/core/http/http-request/index.android.js. Reproduce the POST against the stated http://10.0.2.2:4001/api/Login/Login endpoint, then determine whether the request completes without the reported unexpected end-of-stream error and add a focused regression test if the failure is reproducible.
