BadGateway when asking deployment of a webapp based on container image

Question

As few people I am facing the same issue when I want to create a webapp :
BadGateway status message with these details :

{
    "status": "Failed",
    "error": {
        "code": "Forbidden",
        "message": "The subscription 'XXXXX' is not allowed to create or update the serverfarm.",
        "details": [
            {
                "message": "The subscription 'XXXXX' is not allowed to create or update the serverfarm."
            },
            {
                "code": "Forbidden"
            },
            {}
