dimensionValues.query endpoint returning 500 "Unknown Error"

[Florin Iasinovschi]

Hi Google DCM API team,

We're seeing a consistent 500 "Unknown Error" when calling dimensionValues.query for the activity dimension across all our customer credentials. This started a few days ago; the same requests worked previously.

Affected endpoint:
POST https://dfareporting.googleapis.com/dfareporting/v4/userprofiles/{profileId}/dimensionvalues/query

Request details:
- Profile Id
- Request body:
   
    {
      "dimensionName": "activity",
      "startDate": "2025-10-01",
      "endDate": "2025-10-10"
    }
   

Error response:
{
  "error": {
    "code": 500,
    "message": "Unknown Error.",
    "errors": [
      {}
    ],
    "status": "UNKNOWN"
  }
}

Additional details:
- Occurs regardless of date range, advertiser IDs, or profile ID
- Same error with other dimensionName.
- Tested via the Node.js googleapis client library and direct REST API calls (same error)

Impact:
This regression blocks our measurement data synchronization workflows.

Question:
1. Has there been a recent change or deprecation to dimensionValues.query for the activity dimension?
2. Is there an alternative method to retrieve activity dimension values that have data within a specific date range?
3. Can you confirm if this is a known issue being addressed?

Thank you.
