Error on account creation

[aradhell]

Hello,

I use latest version and also tried to downgrade but ads account creation gives the error below;
We didn't make any code changes and we send all required params.

API Error:
{
"message": "Request contains an invalid argument.",
"code": 3,
"status": "INVALID_ARGUMENT",

"@type": "type.googleapis.com/google.ads.googleads.v22.errors.GoogleAdsFailure",

}
],

]
}
