Issue Arising During File Transfer in Nativescript

I am currently attempting to upload an image that I captured with Nativescript to a server using a web API that I created in C# (ASP.NET). The API works perfectly fine when tested on Postman, but I encounter an error "Error During Upload" while trying to upload from my android device.

Here is the code for the web API:

[HttpPost]
    [Route("PostUserImage")]
    [AllowAnonymous]
    public async Task<HttpResponseMessage> PostUserImage()
    {
        // Code goes here
    }

And this is the code for the Nativescript upload:

// Nativescript upload code goes here

Output

JS: Result is an image asset instance

JS: Image taken!

JS: file path;;;;;;:/storage/emulated/0/Pictures/Test.jpeg

JS: in dock receive
JS: ---------------- JS: Status: progress JS: current bytes transfered: 4096 JS: Total bytes to transfer: 92558 JS:---------------- JS: Status: progress JS: current bytes transfered: 92558 JS: Total bytes to transfer: 92558 JS: ---------------- JS: Status: complete

Answer №1

The issue arises from the fact that the saveToFile() function is within an asynchronous function.

selected.getImage({ maxWidth: 200 }).then((imageSourceS) => 
{
    console.log("A");
});
console.log("B");
// upload code

This is the current structure of your code.

It will first display B and then A.
