OpenAPI Validation Error for Type enum

There is a bug when performing OpenAPI validation for parameters of the enum type. The bug is based on: https://bitbucket.org/atlassian/swagger-request-validator/issues/161/mockmvc-openapi-30-type-of-enum-parameter

The error is recorded as:

[Path ‘/requesterPlmn’] Instance type (string) does not match any allowed primitive type (allowed: [“object”])

This occurs when you send a request to an NRF server that is configured using our HTTP2 Server agent with OpenAPI validation enabled. You will be meet with a Bad Request error (Error 400) and the validation fails. There was an issue with the specifications for the type enum within the 'anyOf' section as seen from the example below.

    NFType:
      description: NF types known to NRF
      anyOf:
        - type: string
          enum:
            - NRF
            - UDM
            - AMF
            - SMF
            - AUSF
            - NEF
            - PCF
            - SMSF
            - NSSF
            - UDR
            - LMF
            - GMLC
            - 5G_EIR
            - SEPP
            - UPF
            - N3IWF
            - AF
            - UDSF
            - BSF
            - CHF
            - NWDAF
            - PCSCF
            - CBCF
            - HSS
            - UCMF
            - SOR_AF
            - SPAF
            - MME
            - SCSAS
            - SCEF
            - SCP
        - type: string

A workaround would be to add the 'type: string' parameter on the same level as the 'anyOf'.

SAP CC Notification Agent TLS Feature Not Working

The fields in SAP CC Notification Agent Configuration for configuring TLS connection are, Enable Secured Connection, Keystore Path and Keystore Password. These fields should not be enabled and used for now as it will cause the agent to fail to connect to the SAP CC server.

OpenAPI Validation Error for Unsupported Optional Parameters in HTTP2 Client

The JSON object/array is not supported in the url-encoded format in OpenAPI Validator library. This causes the access token request sent with such optional fields to be rejected by the OpenAPI validator.

The validation error is prompted as follows:

Error during request validation:
[Path ‘/requesterPlmn’] Instance type (string) does not match any allowed primitive type (allowed: [“object”])
