[BUG] Incorrect errors in LSP

[uroybd]

Describe the bug
Let's consider this example:

### 

# @name LOGIN

POST {{API_URL}}/auth/signin HTTP/1.1
Content-Type: application/json

{
  "email": "{{USERNAME}}",
  "password": "{{PASSWORD}}"
}

###

# @name WS_DETAILS
GET {{API_URL}}/currentWorkspace
Authorization: Bearer {{LOGIN.response.body.*}}

The {{LOGIN.response.body.*}} generates an error in diagnostic: Parsing error in header.
