PUT /vnf_packages/{vnfPkgId}/package_content; Incorrect schema of the request “#/components/requestBodies/VnfPackageContentRequest”

As per the SOL003 (4.3.1) Spec, the VnfPackageContentRequest has no fields / properties prescribed. However, in the swagger (yaml) declarations, the properties “file” is defined as application/binary:

VnfPackageContentRequest:
      content:
        application/binary:
          schema:
            properties:
              file:
                type: file
                description: |
                  The payload body contains a ZIP file that represents the VNF package. The "Content-Type" HTTP header shall
                  be set according to the type of the file, i.e. to "application/zip" for a VNF Package as defined in ETSI GS NFV-SOL 004.
                format: binary
      required: true

This causes the Open-Api Code generator for the Spring-boot to nest a JSON field “file” within a wrapper class: “VnfPackagesVnfPkgIdPackageContentGetRequest.java”

So, the Spring framework rejects the request as Unsupported Media Type “application/zip”. Supported Media Types: [“application/json”]

  }

Fix required: The swagger SOL005/src/SOL005/VNFPackageManagement/VNFPackageManagement.yaml should NOT define a property “file”, given the request content in its entirety is a BINARY (and not a JSON/XML)
