Error during upload

[joey0xx]

Im trying to upload a video (or any file) to a C# dotnet api. When its uploading it shows the progress on the status bar but when it gets to 100%, it shows an error saying 'Error during upload'. I tried debugging the api and the request doesnt go through, but sending the request with the http module it does go through.

Hi @joey0xx With the provided information I am not able to reproduce the issue. I downloaded your application and replaced "url goes here" with the url used in the plugin's demo application. I was able to successfully upload a 55MB video in mp4 format.

Hello @tgpetrov thank you for the response.

I was able to fix the problem earlier, the issue was in the api.

For anyone who might run into this problem using a dotnet core C# api, this is what i did:

[HttpPost()]
public async Task<IActionResult> UploadFile()
{
      var form = Request.Form;

      //gets the files that were sent in the request
      var file = form.Files;

      //create a dictionary that maps the name of the parameter and the value
      var keyValueParams = form.ToDictionary(x => x.Key, x => x.Value.ToString());

      //do whatever else you need to do 
}
