when i am trying to create sponsored brand campaign i am getting error

[
    {
        "code": "INVALID_ARGUMENT",
        "description": "No keywords were successfully created",
        "errors": [
            {
                "KeywordError": {
                    "message": "No keywords were successfully created",
                    "reason": "KEYWORD_CREATION_FAILURE"
                }
            }
        ]
    }
]

here is the requested payload which i am submitting. All the provided detail is accurate may be i am missing some keys to add in it but amazon is not returning any error like that just saying "No keywords were successfully created" with code of "INVALID_ARGUMENT".
