RE: Enabling NLP Understanding Config on Data Store

[priyance]

Hi Community,

Currently, I have created a datastore which is synced with logs stored in bigquery. I am trying to enable naturalLanguageQueryUnderstandingConfig on it and getting below error

 curl -X PATCH -H "Authorization: Bearer $(gcloud auth print-access-token)" -H "Content-Type: application/json" -H "X-Goog-User-Project: $PROJECT_ID" "https://us-discoveryengine.googleapis.com/v1/projects/$PROJECT_ID/locations/us/collections/default_c..." -d '{"naturalLanguageQueryUnderstandingConfig": {"mode": "ENABLED"}}'
{
"error": {
"code": 400,
"message": "Invalid JSON payload received. Unknown name \"naturalLanguageQueryUnderstandingConfig\" at 'data_store': Cannot find field.",
"status": "INVALID_ARGUMENT",
"details": [
{
"@type": "type.googleapis.com/google.rpc.BadRequest",
"fieldViolations": [
{
"field": "data_store",
"description": "Invalid JSON payload received. Unknown name \"naturalLanguageQueryUnderstandingConfig\" at 'data_store': Cannot find field."
}
]
}
]
}
}

Here is the datastore config

curl -X GET -H "Authorization: Bearer $(gcloud auth print-access-token)" -H "Content-Type: application/json" -H "X-Goog-User-Project: $PROJECT_ID" "https://us-discoveryengine.googleapis.com/v1/projects/$PROJECT_ID/locations/us/collections/default_c..."

},
"servingConfigDataStore": {}
}

Am i missing anything? Any help will be appreciated!!
