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:

Error(s) during request validation:

Unable to parse JSON - Unrecognized token'xxx': was expecting (JSON String, Number, Array, Object or token 'null', 'true' or 'false')

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'.
