Problem with reference

[XANDERM]

Hello,

I am working with last versión and I found a problem with upload endpoint file:

If we have the next endpoint:

post:
summary: Creates a remittance and start a bulk process.
description: Creates a remittance and start a bulk process with the purchase orders from the file.
operationId: createRemittancesBulk
tags:
- Remittances
requestBody:
$ref: '#/components/requestBodies/CreateRemittancesBulk'
responses:
'201':
$ref: '#/components/responses/CreateRemittancesBulk'
'400':
$ref: '#/components/responses/BadRequest'
'401':
$ref: '#/components/responses/Unauthorized'
'403':
$ref: '#/components/responses/Forbidden'
'404':
$ref: '#/components/responses/NotFound'
'406':
$ref: '#/components/responses/NotAcceptable'

'500':
$ref: '#/components/responses/InternalServerError'
'503':
$ref: '#/components/responses/ServiceUnavailable'
'504':
$ref: '#/components/responses/GatewayTimeout'
security:
- JWTProfile:
- remittances.CREATE

with this requestBody:

CreateRemittancesBulk:
description: body
required: true
content:
multipart/form-data:
schema:
$ref: '#/components/schemas/RemittanceFile'

and with this reference:

RemittanceFile:
description: Data structure containing remittance file with the purchase orders.
type: object
required:
- file
properties:
file:
type: string
description: File to be uploaded or downloaded.
format: binary
example: attachment; filename="file.media-type"

It work correctly and it create a Multipartfile in request

But if I change the propertie file and I add a reference to File as follow:

RemittanceFile:
description: Data structure containing remittance file with the purchase orders.
type: object
required:
- file
properties:
file:
$ref: '#/components/schemas/File'

with this reference:

File:
type: string
description: File to be uploaded or downloaded.
format: binary
example: attachment; filename="file.media-type"

It will create a Resource (org.springframework.core.io.Resource)

Why is it happened? Shouldn't it create the same object in both??
