Hey everyone,
we’re trying to create a new client via the Google Ads API, but the request
consistently fails with this response:
{
"error": {
"code": 400,
"message": "Request contains an invalid argument.",
"status": "INVALID_ARGUMENT",
"details": [
{
"@type":
"type.googleapis.com/google.ads.googleads.v22.errors.GoogleAdsFailure",
"errors": [
{
"errorCode": {
"requestError": "UNKNOWN"
},
"message": "The error code is not in this version."
}
],
"requestId": "ExNbo7FMI3-ux4gZyG6YhA"
}
]
}
}
All parameters look valid, but the API still returns this UNKNOWN
requestError.
I also reproduced the issue using the official API Test Tool
<https://developers.google.com/google-ads/api/reference/rpc/v22/CustomerService/CreateCustomerClient?transport=rest>
— same result.
Has anyone experienced this recently or figured out what triggers "The
error code is not in this version"?
Could it be related to the API version (v22) or a mismatch in the request
schema?
Any insights would be much appreciated!
