.net – Request variable doesn't work if uses environment variables in .http in Visual Studio 2022 – Stack Overflow

Can someone check if this is a visual studio error or if I made a mistake somewhere?

Desired scenario: first request in each of .http files is login request.
Other requests consume the token from the login request variable.

http-client.env.json:

{
  "$shared": {
      "login": "<login>",
      "pass": "<pass>" 
  },
  "local": {
    "host": "<url:localhost>"
  },
  "dev": {
    "host": "<url:dev>"
  }
}

MyRequests.http:

### Run Login before next queries. 
// @name login
POST {{host}}/api/auth/login HTTP/1.1
Content-Type: application/json

{
    "Login": "{{login}}", 
    "Password": "{{pass}}"
}

### 
GET {{host}}/api/todos
Authorization: Bearer {{login.response.body.$.token}}

Error:

(2,25): error HTTP0012: Unable to evaluate expression 'login.response.body.$.token'.

Everything works if I use constants directly in the .http file for login-password instead of environment variables.

In general, the goal is to store the login and password in a separate file that is not under source control.
