NSwag should not generate an attribute with the default value for query parameters in OAS 3.0

[klacol]

We have a controller with this signature

public IHttpActionResult GetBuildingsWithHseq(string expand = null, bool deactivated = false)
{}

NSwag generates an OAS 3.0 file with the query param "deactivated" like this:

"/api/Hseq/Buildings": {
      "get": {
        "tags": [
          "Hseq"
        ],
        "summary": "Get a list of all buildings that have at minimum one HSEQ function attached",
        "operationId": "Hseq_GetBuildingsWithHseq",
        "parameters": [
          {
            "name": "expand",
            "in": "query",
            "description": "(optional) The csv list of properties to expand in result.",
            "schema": {
              "type": "string",
              "nullable": true
            },
            "x-position": 1
          },
          {
            "name": "deactivated",
            "in": "query",
            "description": "(optional) inclusive deactivated records.",
            "schema": {
              "type": "boolean"
            },
            "x-position": 2,
            "default": false
          }

This is not valid according to https://editor.swagger.io/ and https://speccy.io. A parameter has no attribute with the name "default". See also in the specification.

NSwag should not generate the attribute "default" for query parameters in OAS 3.

[markafox]

the "default" attribute should be inside the "schema"

{
            "name": "deactivated",
            "in": "query",
            "description": "(optional) inclusive deactivated records.",
            "schema": {
              "type": "boolean",
              "default": false
            },
            "x-position": 2
          }

I am facing the same issue. The "default" should be inside "schema" for query parameters.
