"Unknown Error" while creating API spec in Swagger - node.js

Hi I'm creating a Sample API Spec using swagger as below :
I keep getting "Unknown Error on "Items:" line
swagger: "2.0"
info:
version: "0.0.1"
title: Todo API
# during dev, should point to your local machine
host: localhost:10010
# basePath prefixes all resource paths

schemes:
# tip: remove http to make production-grade
- http
- https
# format of bodies a client can send (Content-Type)
consumes:

# format of the responses to the client (Accepts)
produces:
- application/json
paths:
/:
get:
description: "this endpoint returns list of todo events"
operationId: "GetAllTodos"
parameters: []
responses:
200:
description: "an array of all the present todos"
schema:
type: "array"

duedate:
type: "string"
format: "date-time"
description: "time by when the todo event should be completed"
completed:
type: "boolean"
description: "status of todo completion"

Change
$ref: "#definitions/Todo"
to
$ref: "#/definitions/Todo"
Note the / after #.
Also, you are using an old version of Swagger Editor (2.x), which is no longer maintained. Consider using the latest version at http://editor.swagger.io.

Generate swagger server that will server local file

I'm trying to write a yaml that will generate a nodejs stub-server serving a file. Swagger codegen generates server that replies nothing.
swagger: "2.0"
info:
description: ""
version: "1"
title: "Swagger example"
host: "localhost:3200"
basePath: "/v2"
schemes:
- "http"
paths:
/getImage:
get:
tags:
- "image"
summary: "Returns image"
description: ""
operationId: "getImage"
produces:
- "application/octet-stream"
responses:
"200":
description: "successful operation"
schema:
type: "file"
example:
sampleFile:
summary: "A sample file"
externalValue: "http://github.com/topheroes/topheroes.github.io/raw/master/img/dragon.png"
"400":
description: "Invalid value"
Is there a way to generate a stub that will serve a local or a random binary (image) file?
I tried type: string and format: binary, I tried url in example. Nothing seems to work.
Please advice

OpenApi 3.0.2. Spec-file does not have router property

I'm trying to build an API using OpenApi 3.0.2 for active documentation. I've managed to build a validated spec-file, and if I take out all of the OpenApi "stuff" from the API itself, all of the routes work properly, and I have no errors (unless I've managed to change something vital while attempting to solve this problem).
Additionally, my controllers do in fact have the generic controller names that this error suggests I use, so my initial thought was that it's having trouble finding my controllers. However, when I used Swagger 2.0 (before rebuilding it with 3.0), I didn't have this problem.
All of my controllers are structured similarly, and when I changed the order of the controllers (path '/users' first), I retrieved the same error ('users' swapped out for 'garments' in the error log).
That said, I feel that there must be something I'm doing wrong in my "bringing together" of the functioning API and the valid spec-file.
I've been looking for a solution to this problem for a while now, but I have found nothing. If this question has been asked and answered before, I apologize; please redirect me. This is my first StackOverflow question, so please be gentle. If I have missed any information important to the question, please let me know.

Any help is vastly appreciated.
I'll answer this even if it's late because I have had this same problem and looked for a long time the solution. If someone else happens to have any reference on how to fix it.
When you set the controllers parameter in oas-tools:
OasTools.configure({
controllers: `${__dirname}/controllers`,
...
});
The default mapping that oas-tools makes to load the files is endpoint+Controller.js, in your case oas-tools would look for the export function indexGarments in .../controllers/garmentsController.js
Another example would be for the case /garments/{_ id}, the name of the controller file should be garments_idController.js
Using x-router-controller
If you want to use the parameter x-router-controller you have to put it inside the method:
...
/garments:
get:
x-router-controller: garmentsController
operationId: indexGarments
description: Returns an array of garments.
responses:
But be careful because it also modifies the value of the parameter (I do not know if this is a bug or because the name of the files has that requirement), for example, if you configure x-router-controller with the value garments.resource the file to be searched will be .../controllers/garmentsresource.js
In case you set the x-router-controller parameter and the file is not found, this error will be thrown:
info: Valid specification file
info: Specification file dereferenced
debug: Register: GET - /health
debug: GET - /health
debug: OAS-doc has x-router-controller property
error: undefined
For OAS3 you may try this:
paths:
/users:
get:
tags:
- User
x-openapi-router-controller: usersController
description: Returns an array of users.
operationId: indexUsers
responses:
"200":
$ref: '#/components/schemas/User'

Swagger Codegen - Unexpected missing property for name response

Please help. Not sure what I am missing here.
It looks like the error is caused by inline models in responses. While this is perfectly valid, it might be that Swagger Codegen does not support this. You can open an issue in the Swagger Codegen repository.
Try putting the model definitions in the global definitions section, so that your responses section looks like this:
responses:
'200':
description: 'Success Response'
schema:
type: array
items:
$ref: '#/definitions/Message'
'401':
description: Unauthorized requests
schema:
$ref: '#/definitions/Error'
'500':
description: Response for other issues

Cannot resolve the configured swagger-router handler: movie_get

I'm using Swagger with NodeJS, and when I test an example I have this error.
Here is my YAML:

Given your YAML, and assuming you're using swagger-tools with the options given in their tutorials, x-swagger-router-controller: movie will route any requests to GET /movie to a function called get exported from the module /controllers/movie.js in your project. Have you set that up?
Also check your swagger options to check that the correct controllers path is included, e.g. controllers: `${__dirname}`/controllers.

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).
