PDF Services API: Not authorized to call this engine (401)

[WMC-IT]

Hello, 

Using:  "Service Account (JWT)" with "PDF Services API"

Problem:

I can no more use this method: "Export PDF (https://cpf-ue1.adobe.io/ops/:create?respondWith=...) 

I always get the error, "401 Not authorized to call this engine".

{
    "cpf:status": {
        "completed": true,
        "type": "UNAUTHORIZED",
        "title": "Not authorized to call this engine",
        "status": 401,
        "report": "{\"error_code\":\"UNAUTHORIZED_ENGINE_ACCESS\"}"
    }
}

Nothing is changed, excepting generate new Public/Private key.

Is this method no more working since marked as deprecated?

The call will be make over PHP (Guzzle), I have also tested over Postman and there I get the same error.

I hope someone can help me.

Thanks.
