swagger-node - Error: Response validation failed: void does not allow a value

I'm using swagger-node library, and am trying to achieve a 302 redirect with it. But it results into the error described in the title.

My schema regarding the path looks following:

  /login:
    x-swagger-router-controller: login
    get:
      produces:
        - text/html
      description: Entry point for login
      operationId: login
      responses:
        "302":
          headers:
            Location:
              type: "string"
          description: Found

In my api, I have express app, and I'm just redirecting like so:

res.redirect(redirect_url);

How could I achieve redirect using swagger-node?

Stacktrace is following:

Don't know if you already figured it out, but to make 302 response work, u have to define the schema type from the response as a string

responses:
  "302":
    description: "302 response"
    schema:
      type: string
