Multipart form data cannot be validated has object

[Fimeo]

Hi!

I got an issue when I want to use the multipart form data content type to send a file.

I am using gin with getkin middleware to validate input requests.

The swagger defintion contains theses values:

post:
  operationId: saveUploadedFile
  tags:
  - Upload
  responses:
    '200':
      description: File successfully uploaded
  description: Upload a file to the storage bucket.
  requestBody:
    content:
      multipart/form-data:
        schema:
          type: object
          properties:
            upload:
              format: binary
              type: string
          required:
          - upload
    required: true

I have registered the multipart decoder :

openapi3filter.RegisterBodyDecoder("multipart/form-data", openapi3filter.FileBodyDecoder)

But with a curl like:

curl --location --request POST 'http://localhost:8080/uploads' \
--header 'accept: application/json' \
--header 'Content-Type: multipart/form-data' \
--form 'upload=@"/file.jpg"'

I still got the validation openapi3filter.RequestValidationInput with reason doesn't match schema, value must be an object.

But the input request has a object input and gin could find the form file using context.FormFile("upload").

Did I missed something about multipart definition?

Thanks :D

Delete openapi3filter.RegisterBodyDecoder("multipart/form-data", openapi3filter.FileBodyDecoder)
