Need assistance fixing a websocket error I keep getting. I am running nginx as a proxy.
Trying to perform the initial data migration using migrator but I get a null reference exception after fixing the data types. I tried deleting all the migrations but when migrating the database only the EF table gets created.
I am trying to deploy ASPNETZERO to Digital Ocean but I am getting an error. Here is the docker file on the host folder: #See https://aka.ms/containerfastmode to understand how Visual Studio uses this Dockerfile to build your images for faster debugging.

I'm try to request a download genearting a url query string. i found angular code within the project (file-download helper)The second method is the one I created, when calling this method I get an auth error on the core side.( INFO 2020-08-27 16:54:58,612 [5 ] Microsoft.AspNetCore.Hosting.Diagnostics - Request starting HTTP/2 GET https://localhost:44301/FileManager/GetFile?fileName=lvweb01.zip&fileToken=6c3041bd-a1f6-1634-121d-f0252cb4cb3d INFO 2020-08-27 16:54:58,632 [5 ] uthorization.DefaultAuthorizationService - Authorization failed).

I'm trying to download large files with the following code which returns a blob from .netcore 3.1
downloadFile(id): void {
let filedownloadInput = new FileDownloadInput();
filedownloadInput.id = id;
this._FileManagerService.downloadFile(filedownloadInput).subscribe(item => {
this.InitializeDownload(item.fileName, item.fileToken).subscribe((data: any) => {
var downloadURL = window.URL.createObjectURL(data);
var link = document.createElement('a');
link.href = downloadURL;
link.download = item.fileName;
link.click();
});
});
}
This works for small files (<10mb) but when large files are inbound, the response being saved to browser memory takes too long. I know that this method doesn't save directly to the filesystem, as it passes through the browser first, but is there a way to bypass saving the entire blob to browser memory first? So it seems like the browser caches the file first at which point the user does'nt see anything. You can only see the transfer with dev tools. Once it downloads to the browser memory then I can see the file downloading on the browser.
On the angular side I have the below code. Once the method subscribes (InitializeDownload()) I can see the download on the developer tools under network
once the transfer is done the code under subscribe method executes
when looking at the serve logs
WARN 2020-06-17 09:57:07,055 [23 ] nostics.DeveloperExceptionPageMiddleware - The response has already started, the error page middleware will not be executed.

Second part of code is the asp.netcore
I can't figure out why it makes two request and why it takes really long for the download to start.

Hello,
Is it possible to have a windows client app running signal R communicate with ASP.NET Zero. I want to be able to send calls to the app and transfer files between both. What are the limitations and recommendations. Appreciate any light you can shed on this issue.
Working on ASPNet Core and Angular version 6.8 and getting CORS policy error. See error message below, any help with this request would be greatly appreciated.
