Expected input credential was not present

[cclive]

Hello,

I am seeing below issues from the postman with the api call "https://sandbox.api.visa.com/pav/v1/cardvalidation".   This api is MLE Mandatory.  I have imported the cert.pem and key's to postman with username and password.  Any suggestions to resolve this from postman?

        "severity": "ERROR",

        "message": "Expected input credential was not present",

        "info": ""

    }

}
