[Deleted user]

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

We have this error

web API .net Core 3

    [HttpPost("attachement")]
    public async Task<ActionResult> UploadAttachement([FromForm] IFormFile file)
    {
        var attachement = new modelProfile
        {

            await stream.ReadAsync(attachement.content, 0, (int)file.Length);
        };

        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: gotev/android-upload-service#549 (which points to a StackOverflow question and a few answers). Worth keeping an eye on it.

I will check it.
Thank you
