Angular 5.1.1 infinite refresh loop after set proxy for signalr?

Question

I'm working with Angular 5.1.1 and @angular/cli ^1.6.1.
I want to use Asp.Net Core SignalR.
So I have the following proxy setting:

const PROXY_CONFIG = [
  {
    context: [
      "/api",
      "/Temp",
      "/Upload",
      "/notificationHub",
      "/sockjs-node"
    ],
    target: "http://localhost:52918/",
    changeOrigin: true,
    secure: false,
    logLevel: 'debug',
    ws: true
  }
];

module.exports = PROXY_CONFIG;

I start project with ng serve --proxy-config proxy.config.js command
But upon http://localhost:4200/ comes up, I get the following message in command line and page refresh and this repeat until infinite

[HPM] POST /api/Category/GetAll/ -> http://localhost:52918/
[HPM] POST /api/Product/GetAllActives/ -> http://localhost:52918/
[HPM] OPTIONS /notificationHub -> http://localhost:52918/
[HPM] GET /notificationHub?id=dedf5495-4438-4a9a-9742-d4b16fe0c94b -> http://localhost:52918/

Finally I could find the solution
I have to change proxy config as follows:

const PROXY_CONFIG = [
  {
    context: [
      "/api",
      "/Temp",
      "/Upload",
      "/notificationHub"
    ],
    target: "http://localhost:52918/",
    secure: false,
    logLevel: 'debug',
    ws: true
  }
];

It's OK now
