[MVExtensions] VSC: trying to connect through gateway

[philippe GRACIA]

Hello !

Clément and I are trying to us VsCode with D3 Linux, We are new programmers in pick.

We followed the tutorial, and we are trying to debug the Gateway connection, as we have problems connecting to d3.

The gateway is installed and operating.on port 9005.

when we try to connect to gateway, we have a 500 error...
what are we doing wrong ?

Thanks by advance and greetings from france

here is the request:
POST http://localhost:9005/login
Content-Type: application/json

{
 "ServerType": "D3",  
   "RemoteHost": "192.168.2.4",
   "UserName" : "dm",
   "Password" : "",
   "AccountPassword" : "",
   "Account": "webservice"
}
