REST API - Upload File error via C#

[camaralima]

Describe the bug
First of all, the example provided in the File Upload documentation is incorrect, such as adding the Bearer token twice, and the File parameter is set as text. The test via the web page also always results in an error.
Using Postman, the web interface, and Python with HTTP Client, I am able to successfully upload the file and later perform the Get request without any issues. However, when it comes to C# .Net, it doesn't work. The example and simple Upload implementation just return an error.
Could you provide a simple File Upload example?

Job ID
I don't have a Job ID because it was not generated in any of the tests via C#.
This is the ID using Python HTTP Client db95fba2-5ee0-4fff-95b6-708256ced7c9, and this is the ID using the library in Python 5b5f13bc-31d3-4420-af65-130652bdcacf.

Additional context
The error:

BadRequest - {"detail":"There was an error parsing the body"}

Below is the snippet of my code that is throwing an error:

public static async Task UploadFileAsync(byte[] byteArrayFile, FileStream fileStream, string fileName)
{
    string url = _baseUrl + _baseUrlUpload; 

    using (HttpClient client = new HttpClient())
    {
        client.DefaultRequestHeaders.Authorization = new AuthenticationHeaderValue("Bearer", _apiKey);

        using (var content = new MultipartFormDataContent())
        {
            var fileContent = new ByteArrayContent(byteArrayFile);
            //var fileContent = new StreamContent(fileStream); 

            content.Add(fileContent, "file", fileName);
            content.Add(new StringContent("true"), "fast_mode");
            content.Add(new StringContent("en"), "language"); 

            try
            {
                HttpResponseMessage response = await client.PostAsync(url, content); 

                string responseContent = await response.Content.ReadAsStringAsync(); 

                if (response.IsSuccessStatusCode)
                {
                    Console.WriteLine(responseContent);
                }
                else
                {
                    Console.WriteLine($"Fail to send file: {response.StatusCode} - {responseContent}");
                }
            }
            catch (Exception ex)
            {
                Console.WriteLine($"Error: {ex.Message}");
            }
        }
    }
}

Or when I make any changes that return an ID, I get the following error:

{
    "id": "a2a0480d-0a9e-4c28-b057-18dcfb3fe46d",
    "status": "ERROR",
    "error_code": "_UNKOWN_ERROR",
    "error_message": "UNKNOWN_ERROR: COULD_NOT_LOAD_FILE"
}
