Document AI processor cannot be removed

[oleks_vasyliev]

Hello. I am trying to remove "Custom Extractor", which contain "general ai" models, but GCP console give error "GenAI 1P model can not be deleted from model registry, delete it from tuning side".  Trying to remove model also provide same error:

{
  "name": "projects/950151893526/locations/us/operations/8534504841544376159",
  "done": true,
  "result": "error",
  "response": {},
  "metadata": {
    "@type": "type.googleapis.com/google.cloud.documentai.uiv1beta3.DeleteProcessorVersionMetadata",
    "commonMetadata": {
      "state": "FAILED",
      "createTime": "2024-07-24T04:44:35.241570Z",
      "updateTime": "2024-07-24T04:44:35.644815Z",
      "resource": "projects/950151893526/locations/us/processors/11306dc53677b820/processorVersions/b6deccc5f9196d09"
    }
  },
  "error": {
    "code": 3,
    "message": "GenAI 1P model can not be deleted from model registry, delete it from tuning side.",
    "details": []
  }
}

I searched for "tuning side" over GCP interface and cannot find where it is. Also no info in documentation bout such error message. How exactly can I remove processor without this error?

Thanks
