I want to pass Url

parameters of a json string for handshaking via

Web Socket in c#. The uri contains query string parameters and it is a json string.While trying to connect I am getting the exception that the URI scheme is not valid

Current WSI Url not working:
("wss://10.15.1.1/Test/sample/{038}?entityDetails={"requestData":"test","requestkData": "tested"}")

WSI uri if as below it works, but without the parameters if passed to the server it works.
"wss://10.15.1.1/Test/sample/

What I have tried:

Core Connectivity Code is as below:

#region Connect
      public async Task Connect(string uri)
      {


          Thread.Sleep(1000); //wait for a sec, so server starts and ready to accept connection..

          try
          {

              webSocket = new ClientWebSocket();

              await webSocket.ConnectAsync(new Uri(uri), CancellationToken.None);


          }
          catch (Exception ex)
          {



              throw ex;



          }
          finally
          {
              if (webSocket != null)
                  webSocket.Dispose();

          }



      }
      #endregion
