[@nativescript/background-http] error Context.startForegroundService() did not then call Service.startForeground()

[ghost]

Hello, We are using @nativescript/background-http on NativeScript with Angular to upload photos, web API .net Core 3.1

We have this error

System.err: An uncaught Exception occurred on "main" thread. System.err: Context.startForegroundService() did not then call Service.startForeground(): ServiceRecord{6fabfc7 u0 it.openweb.next2u/net.gotev.uploadservice.UploadService} System.err: System.err: StackTrace: System.err: android.app.RemoteServiceException: Context.startForegroundService() did not then call Service.startForeground(): ServiceRecord{6fabfc7 u0 it.openweb.next2u/net.gotev.uploadservice.UploadService} System.err: at android.app.ActivityThread$H.handleMessage(ActivityThread.java:2052) System.err: at android.os.Handler.dispatchMessage(Handler.java:107) System.err: at android.os.Looper.loop(Looper.java:214) System.err: at android.app.ActivityThread.main(ActivityThread.java:7710) System.err: at java.lang.reflect.Method.invoke(Native Method) System.err: at com.android.internal.os.RuntimeInit$MethodAndArgsCaller.run(RuntimeInit.java:516) System.err: at com.android.internal.os.ZygoteInit.main(ZygoteInit.java:950)

        };

        await serviceUpload.uploadProfile(attachement);

        return Ok();
    }

Can you please help with this error and the way to fix it? Thank you

I get this too, sometimes. Base/Original android project has very similar issue: https://github.com/gotev/android-upload-service/issues/549 (which points to a StackOverflow question and a few answers). Worth keeping an eye on it.
