Video Upload API only works with 1 file type?

I have a script that uploads a video to an API I built, and after it processes on the API side, a text file is returned to the client. The strange thing is, this only works with one type of file, a .QT file extension. Any other video type I try to send sends and empty video. I have tried .mov, .mp4, and .qt and only the .qt uploads properly. I'll post my code below. Would anyone know what cause only the one file type to work? Nothing on the API side singles out the qt file. I believe this is an issue with this script.
public async void Function() {
Debug.Log("works1");
string filePath = "IMG_0491.mov";
//string filePath = ProcessMode.theFilePath;
var client = new HttpClient();
using (var multipartFormContent = new MultipartFormDataContent()) {
//Add the file
Debug.Log("works2");
var fileStreamContent = new StreamContent(File.OpenRead(filePath));
Debug.Log("works3");
fileStreamContent.Headers.ContentType = new MediaTypeHeaderValue("video/mov");
multipartFormContent.Add(fileStreamContent, name: "file", fileName: filePath); //Originally Actual "Name`
//Send it
var response = await client.PostAsync("http://127.0.0.1:5000/", multipartFormContent); //Enter IP and Port of API when set up
Debug.Log("works4");
//Ensure it was successful.
response.EnsureSuccessStatusCode();
//Grab the animation data from the content.
var animation_data = await response.Content.ReadAsStringAsync();
Debug.Log(animation_data);
//Save to file.
//File.WriteAllTextAsync("AnimationFile.txt", animation_data);
await File.WriteAllTextAsync("AnimationFile.txt", animation_data);
Debug.Log("works5");

How to attach a file to a form in Unity?

I am currently trying to make a post request with a file attached to the form but I found out that it is not the file I have attached but just the path to the file.
My question is how do I get this file and attach it to the form?
Here is my code so far:
string altPath = Path.Combine(Application.persistentDataPath, "nice-work.wav");
List<IMultipartFormSection> formData = new List<IMultipartFormSection>();
formData.Add(new MultipartFormFileSection("wavfile", altPath));
UnityWebRequest uwr = UnityWebRequest.Post(url, formData);
yield return uwr.SendWebRequest();
if (uwr.isNetworkError)
{
Debug.Log("Error While Sending: " + uwr.error);
}
else
{
Debug.Log("Received: " + uwr.downloadHandler.text);
}
the variable altPath is the path but not the file and this leads to failed post request.

If you look at MultipartFormFileSection the constructor you are currently using is
MultipartFormFileSection(string data, string fileName)
which is of course not what you want to do.
You rather have to actually read the according file content e.g. simply using File.ReadAllBytes
...
var multiPartSectionName = "wavfile";
var fileName = "nice-work.wav";
var altPath = Path.Combine(Application.persistentDataPath, fileName);
var data = File.ReadAllBytes(altPath);
var formData = new List<IMultipartFormSection>
{
new MultipartFormFileSection(multiPartSectionName, data, fileName)
};
...
or depending on your server side needs
...
var formData = new List<IMultipartFormSection>
{
new MultipartFormFileSection(fileName, data)
};
...
Though have in mind that ReadAllBytes is a synchronous (blocking) call and for larger files you might rather want to use some asynchronous approach.

How can I create headers for a text file and upload it with httpClient?

My text file is saved on my hard disk and I want to upload it in Visual Studio to this file management service: https://learn.microsoft.com/en-us/gaming/playfab/features/data/content-delivery-network/quickstart#fetching-assets
Before uploading, I want to create the file headers, because I want to add a version number of the file to the headers. For example, I want to add "1" to the headers, if it is the first version. How can I do that?
After that, I want to upload the text file. But I don't know how to upload the file with httpClient. How can I upload the file?
I have tried it with this code, but it's not working and I don't know what I'm doing wrong. What is wrong?
private async Task UpoadNewContent()
{
var result = await PlayFabAdminAPI.GetContentUploadUrlAsync(new GetContentUploadUrlRequest()
{
Key = "Levelfiles/Level2.txt",
ContentType = "binary/octet-stream"
});
if (result.Error != null)
{
Console.WriteLine("Error.");
}
else
{
Uri webService = new Uri(result.Result.URL + "Levelfiles/" + "Level2.txt");
await UploadFileAsync(webService, "/Users/myname/TESTFOLDER/Level2.txt");
}
}
async Task UploadFileAsync(Uri uri, string filename)
{
using (var stream = File.OpenRead(filename))
{
var client = new HttpClient();
var response = await client.PostAsync(uri, new StreamContent(stream));
response.EnsureSuccessStatusCode();
}
}
I get this response:

Send a 'Stream' over a PutAsync request

I'm trying my hand at .NET Core but I'm stuck trying to convert multipart/form-data to an application/octet-stream to send via a PUT request. Anybody have any expertise I could borrow?
[HttpPost("fooBar"), ActionName("FooBar")]
public async Task<IActionResult> PostFooBar() {
HttpResponseMessage putResponse = await _httpClient.PutAsync(url, HttpContext.Request.Body);
}
Update: I think I might have two issues here:
My input format is multipart/form-data so I need to split out the file from the form data.
My output format must be application-octet stream but PutAsync expects HttpContent.

I had been trying to do something similar and having issues. I needed to PUT large files (>1.5GB) to a bucket on Amazon S3 using a pre-signed URL. The implementation on Amazon for .NET would fail for large files.
Here was my solution:
static HttpClient client = new HttpClient();
client.Timeout = TimeSpan.FromMinutes(60);
static async Task<bool> UploadLargeObjectAsync(string presignedUrl, string file)
{
Console.WriteLine("Uploading " + file + " to bucket...");
try
{
StreamContent strm = new StreamContent(new FileStream(file, FileMode.Open, FileAccess.Read));
strm.Headers.ContentType = new System.Net.Http.Headers.MediaTypeHeaderValue("application/octet-stream");
HttpResponseMessage putRespMsg = await client.PutAsync(presignedUrl, strm);
}
catch (Exception e)
{
Console.WriteLine(e.Message);
return false;
}
return true;
}

Turns out Request has a Form property that contains a Files property that has an OpenReadStream() function on it to convert it into a stream. How exactly I was supposed to know that, I'm not sure.
Either way, here's the solution:
StreamContent stream = new StreamContent(HttpContext.Request.Form.Files[0].OpenReadStream());
HttpResponseMessage putResponse = await _httpClient.PutAsync(url, stream);

https://do.convertapi.com/Pdf2PowerPoint without providing physical file location

I am calling API
https://do.convertapi.com/Pdf2PowerPoint
Their website for the API details is
https://www.convertapi.com/
To upload the file in their C# documentation they have used client.UploadFile() function which expects file name parameter from physical location. in my case i have bytes of PDF file coming on the fly without storing that to physical location and I want to upload that bytes instead. I am using client.UploadData() function which expects byte array and I have provide that. but their API is throwing error and is asking to provide File name which is must.
I think Developers of API would only be able to answer. But if you guys have any idea if I am doing any mistake to upload file. please suggest your workaround.
Please find my code below as requested
var client = new WebClient();
var data = new NameValueCollection();
data.Add("OutputFileName", "TestOutput.pptx"); //Optional
data.Add("File", "Revised.pdf");
data.Add("ApiKey", "484700111"); //API Key must be set if you purchased membership with credits. Please login to your control panel to find out your API Key http://www.convertapi.com/prices
try
{
client.QueryString.Add(data);
client.Headers.Add("Content-Type", "application/x-www-form-urlencoded");
//I am using ReadAllBytes Approach for now as in my practical scenario I am going to get bytes instead of sending file from Physical location
byte[] Arr = File.ReadAllBytes(#"D:\PPTTest\Level I and II Revised.pdf");
// Error here : File Parameter can not be null
var response = client.UploadData("https://do.convertapi.com/Pdf2PowerPoint", Arr);
var responseHeaders = client.ResponseHeaders;
var path = Path.Combine(#"D:\PPTTest\", responseHeaders["OutputFileName"]);
File.WriteAllBytes(path, response);
//Console.WriteLine("The conversion was successful! The word file {0} converted to PDF and saved at {1}", fileToConvert, path);
}
catch (WebException e)
{
Console.WriteLine("Exception Message :" + e.Message);
if (e.Status == WebExceptionStatus.ProtocolError)
{
Console.WriteLine("Status Code : {0}", ((HttpWebResponse)e.Response).StatusCode);
Console.WriteLine("Status Description : {0}", ((HttpWebResponse)e.Response).StatusDescription);
}
}
Thanks,

Code taken from this post. You have to upload file with multipart/form-data request like this:
HttpClient httpClient = new HttpClient();
MultipartFormDataContent form = new MultipartFormDataContent();
form.Add(new StringContent(username), "username");
form.Add(new StringContent(useremail), "email");
form.Add(new StringContent(password), "password");
form.Add(new ByteArrayContent(imagebytearraystring, 0, imagebytearraystring.Count()), "profile_pic", "hello1.jpg");
HttpResponseMessage response = await httpClient.PostAsync("PostUrl", form);
