Swagger Editor - Additional Properties Error - openapi

Question

I'm just starting to use Swagger Editor/OpenAPI 3 spec and so it's not going good so far. I have installed and running Swagger Editor v. 3.15.2 on my local machine.
This is the yaml I have so far:
openapi: "3.0.0"
info:
version: 1.0.0
title: Test
paths:
/object:
post:
summary: Create an object
operationId: createObject
requestBody:
required: true
content:
application/json:
schema:
$ref: "#/components/schemas/Object"
responses:
'201':
description: Created
components:
schemas:
Object:
required:
- name
- description
properties:
name:
type: string
description:
type: string
And it's displaying this error:
Errors
Resolver error
e is undefined
Structural error at paths./object
should NOT have additional properties
additionalProperty: responses
Jump to line 6
Structural error at paths./object.post
should have required property 'responses'
missingProperty: responses
Jump to line 7
I have ensured that I am using two spaces for all the indents. When I copied the yaml from the editor and put it into Notepad++ it looked fine. I also pasted it into another editor and noticed that it only used line feeds and not carriage returns. I updated it to use both and still get the same error.
I have looked at other questions with the same problem but none of the solutions worked for me. So, not sure what I'm doing wrong. Any guidance is greatly appreciated.

Answer 1

You have a small indentation problem.
Add one indentation level to
responses:
'201':
description: Created
So that you then have:
openapi: "3.0.0"
info:
version: 1.0.0
title: Test
paths:
/object:
post:
summary: Create an object
operationId: createObject
requestBody:
required: true
content:
application/json:
schema:
$ref: "#/components/schemas/Object"
responses:
'201':
description: Created
components:
schemas:
Object:
required:
- name
- description
properties:
name:
type: string
description:
type: string
