Swagger validation failed in Yaml file - node.js

Question

I have a swagger yaml specification like this :
swagger: "2.0"
info:
version: "0.0.1"
title: Chat API
# during dev, should point to your local machine
host: localhost:5000
# basePath prefixes all resource paths
basePath: /api/v2
#
schemes:
# tip: remove http to make production-grade
- http
- https
# format of bodies a client can send (Content-Type)
consumes:
- application/json
# format of the responses to the client (Accepts)
produces:
- application/json
paths:
/room:
post:
summary: Get room
operationId: getRoom
tags:
- room
parameters:
-
name: token
in: header
description: "token to be passed as a header"
default: "ZjE4YjMxNmY3OGEzNDMyN2JiYjJmYTQwMDBjODg4OWM="
required: true
-
name: room_id
in: body
description: "get room"
required: true
schema:
$ref: "#/definitions/Room"
definitions:
Room:
required:
- room_id
properties:
room_id:
type: string
This yaml file is compiled well without the header part. If I include the header in the paramerts . The nodejs app keep throwing : "Swagger validation errors"
-
name: token
in: header
description: "token to be passed as a header"
default: "ZjE4YjMxNmY3OGEzNDMyN2JiYjJmYTQwMDBjODg4OWM="
required: true
I don't know what was wrong in this part. I want to add the header to this spec file.

You simply need to add the type attribute. Swagger doesn't know if this is a string, an integer, etc. (although one could say the default explains it).
- name: token
in: header
description: "token to be passed as a header"
default: "ZjE4YjMxNmY3OGEzNDMyN2JiYjJmYTQwMDBjODg4OWM="
required: true
type: string
