Rails strong params handle in YAML - ruby-on-rails

Question

I'm making API documentation on swagger and using YAML.
This is my YAML code
swagger: "2.0"
info:
title: Sign_up Api
description: This Will alow user to Signup.
version: 1.0.0
host: e9ea53234b75.ngrok.io
basePath: /customer_app/api/v1
schemes:
- https
paths:
/sign_up:
post:
summary: Return User Credentials After signup.
parameters:
- in: body
name: body
required: true
# type: string
schema:
type: object
properties:
email:
type: string
example: test123#gmail.com
password:
# type: string
example: test123
password_confirmation:
# type: integer
example: test123
name:
type: string
example: testabc
description: User can be signup by providing the listed params & it will return a authentication token and other user params.
produces:
- application/json
responses:
200:
description: User credentials.
properties:
id:
type: string
example: 70020ed1-50fe-4c7e-afed
password:
# type: string
example: pasw123
password_confirmation:
# type: string
example: pasw123
name:
type: string
example: testabc
422:
description: The specified email is invalid (e.g. not following the syntax) or paswwords are not same or missing params.
default:
description: Unexpected error
and im getting my params in rails by
params.require(:user).permit(:email, :password , :password_confirmation, :uuid, :name)
in this way I'm sending my params from the postman
and getting this response
<ActionController::Parameters {"user"=><ActionController::Parameters {"email"=>"moon123#gmail.com", "password"=>"moon123", "password_confirmation"=>"moon123", "name"=>"moon123"} permitted: false>, "format"=>:json, "controller"=>"customer_app/api/v1/registrations", "action"=>"create"} permitted: false>
but by using user[email] in YAML got this in a wrong way
<ActionController::Parameters {"user[email]"=>"test123#gmail.com", "user[password]"=>"test123", "user[password_confirmation]"=>"test123", "user[name]"=>"testabc", "format"=>:json, "controller"=>"customer_app/api/v1/registrations", "action"=>"create", "registration"=>{"user[email]"=>"test123#gmail.com", "user[password]"=>"test123", "user[password_confirmation]"=>"test123", "user[name]"=>"testabc"}} permitted: false>
I don't know how to edit my YAML to get the response as I got from Postman.

Postman's "form-data" bodies are for requests with Content-Type: multipart/form-data. In OpenAPI 2.0, such requests need to have consumes: [multipart/form-data], and the body fields are defined as in: formData parameters.
swagger: '2.0'
...
paths:
/sign_up:
post:
summary: Return User Credentials After signup.
consumes:
- multipart/form-data
parameters:
- in: formData
name: user[email]
type: string
format: email
x-example: test123#gmail.com
- in: formData
name: user[password]
type: string
format: password
x-example: test123
- in: formData
name: user[password_confirmation]
type: string
format: password
x-example: test123
- in: formData
name: user[name]
type: string
x-example: testabc
