Unable to mutate Life Event criterion to Display ad group

[Jamie Addessi]

I'm having trouble with the Google Ads API (v21) when I try to add Life Event Criterion to an Ad Group on Display Campaigns.
I've tried adding the same criterion through the UI and it succeeds, but when I try to add the criterion in the API I get the following error:

{
  "errorCode": {
    "criterionError": "UNKNOWN"
  },
  "message": "The error code is not in this version.",
  "trigger": {
    "int64Value": "95005"
  },
  "location": {
    "fieldPathElements": [
      {
        "fieldName": "operations",
        "index": 0
      },
      {
        "fieldName": "create"
      },
      {
        "fieldName": "life_event"
      },
      {
        "fieldName": "life_event_id"
      }
    ]
  },
  "details": {
    "unpublishedErrorCode": "CriterionError.INVALID_LIFE_EVENT"
  }
}

Is this feature is supported in the current version of the API? If so, why this error?

Hi,

Thank you for reaching out to the Google Ads API forum.

I understand that you are getting INVALID_LIFE_EVENT error. Unfortunately, this case wasn’t routed to our support queue. Having said that, can you please directly email us to 'googleadsa...@google.com' along with your complete API logs (request and response with request-id and request header) and details about this issue you are encountering so we can better investigate this on our end.

If you are using a client library and haven't enabled the logging yet, I would request you to enable logging for the specific client library that you are using. You can refer to the guides Java, .Net, PHP, Python, Ruby or Perl to enable logging at your end. For REST interface requests, you can enable logging via the curl command by using the -i flag.

We highly appreciate your patience and understanding. Rest assured that we will further assist you on this matter.

Regards,
Google Ads API Team
