Duplicate identifier for parameters with the same name but different location/in

I am using an OpenAPI v3 spec generated by NSwag where the Parameters Object of one of the Operations has two parameters with the same name, but with different Locations (“in”: “query” vs. “in”: “path”)

According to the spec, this should be valid: “A unique parameter is defined by a combination of a name and location.”

When I generate code for this spec, the code has a typescript error “error TS2300: Duplicate identifier”.

...
    "/MyPath/{myParam}": {
      "get": {
        ...,
        "parameters": [
          {
            "name": "myParam",
            "in": "query",
            "schema": {
              "type": "string",
              "nullable": true
            },
            "x-position": 1
          },
          {
            "name": "myParam",
            "in": "path",
            "required": true,
            "schema": {
              "type": "string"
            },
            "x-position": 2
          }
        ],
...

Seeing a similar issue here:

"impersonationUserId": {
      "name": "User-Id",
      "in": "header",
      "type": "string",
      "format": "uuid",
      "required": false,
      "description": "",
      "x-example": "User123"
    },

and:

"userId": {
      "name": "userId",
      "in": "path",
      "type": "string",
      "format": "uuid",
      "required": true,
      "description": "",
      "x-example": "User123"
    },

Both are output as userId on the options object because they have a similar “name” property. But one is in the header and one is in the path.
