[Typescript-Angular2] Generation of POST parameter with "array" schema causes Error.

Description

This problem appeared in v.2.2.3.
I'm trying to generate "typescript-angular2" client API with http://generator.swagger.io/#!/clients/generateClient service.
I cutted my configuration to make it more readable and it looks like this:

{
    "spec": {
        "swagger": "2.0",
        "info": {
            "version": "v1",
            "title": "Star.Web.Api"
        },
        "host": "localhost:5000",
        "schemes": ["http"],
        "paths": {
            "/api/notifications/read": {
                "put": {
                    "tags": ["Notifications"],
                    "summary": "Mark notifications as read",
                    "operationId": "Notifications_PutMultiRead",
                    "consumes": ["application/json", "text/json", "application/x-www-form-urlencoded"],
                    "produces": [],
                    "parameters": [{
                        "name": "ids",
                        "in": "body",
                        "description": "UID's of notifications",
                        "required": true,
                        "schema": {
                            "type": "array",
                            "items": {
                                "type": "string"
                            }
                        }
                    }],
                    "responses": {
                        "204": {
                            "description": "No Content"
                        }
                    },
                    "security": [{
                        "oauth2": []
                    }]
                }
            }
        }
    },
    "options": {
        "modelPropertyNaming":"camelCase",
        "apiPackage":"app.webapi.api",
        "modelPackage":"app.webapi.model"
    }
}

Such a description leads to an error:

{
  "code": 1,
  "type": "error",
  "message": "Unable to build target: Could not generate api file for 'Notifications'"
}

That's because of the schema of my parameter:

"schema": {
    "type": "array",
    "items": {
        "type": "string"
    }
}

If I change it to object or to constant, everything OK. For example:

"schema": {
    "type": "string"
}

The Swagger spec say's that such a schema for parameter is absoluty legal:
https://swagger.io/specification/#parameterIn (see example where body parameter is an array of string values)

Swagger-codegen version

2.2.3

We're seeing the same thing after switching to 2.2.3. However, it's not limited to TypeScript-Angular, we can reproduce for TypeScript-fetch and csharp.
