[background-http] events not fired on device

Hi,

I try to upload an image to a Server via backtround-http. It works correct on android and on iOS-Simulator, but on a real iOS-device, the task-events are not fired.

• "@nativescript/ios": "8.1.0",
  

• "@nativescript/background-http": "^5.0.2",
  

• "@nativescript/core": "~8.1.5",
  

Simulator: iOS 15.2
Device: iOS 15.2.1

const bghttp = require("@nativescript/background-http");
let session = bghttp.session("file-upload");
let request = {
        url: this.backendURL + "images/",
        method: "POST",
        headers: imageHeaders,
        description: "multipart/form-data",
    }
let params = [
        { name: "file", filename: imagePath, mimeType: "image/png" }
    ];
let task = session.multipartUpload(params, request);
task.on("progress", function(e) {
            console.log("uploaded " + e.currentBytes + " / " + e.totalBytes);
        });

    task.on("error", function(e) {
        console.log("error!");
        console.log(e);
        console.log(e.response);
    });

    task.on("responded", function(request) {
        console.log("responded");
    }

Any ideas?

I can not reproduce it on severall smartphones/ipads, but have one device with this behavior...

首先，使用列出的 NativeScript、iOS 和 background-http 版本，在實際的 iOS 裝置上重現 multipart 上傳，然後將其 progress、error 和 responded 回呼與模擬器進行比較。完成標準是找出受影響裝置上為何沒有 task 事件，並確認這些回呼在上傳時能正確運作。
