Filtering by profileId on /duplicateOPERASubscriptions always returns empty list

[ezequielcsilva]

The OpenAPI specification (property/crm.json) documents that
GET /crm/v1/duplicateOPERASubscriptions supports filtering by profileId.

However, any request that includes profileId always returns an empty list,
even when the same profile clearly appears in a duplicated subscription group.

Working request (no profileId)

GET /crm/v1/duplicateOPERASubscriptions?databaseId=TEST_ORS

Response (excerpt)

{
  "duplicateOPERASubscriptionsList": [
    {
      "externalProfileId": { "id": "99000123" },
      "profileSubscriptions": [
        { "profileId": { "id": "55500011" } },
        { "profileId": { "id": "55500022" } }
      ]
    }
  ]
}

This confirms the duplicated subscription group exists.

Failing request (with profileId)

GET /crm/v1/duplicateOPERASubscriptions?databaseId=TEST_ORS&profileId=55500011

Response

{
  "duplicateOPERASubscriptionsList": [],
  "totalResults": 0
}

Even though profile 55500011 or 99000123 is clearly part of a duplication group,
the endpoint returns no results.

Issue Summary

The profileId filter does not work as described in the published API spec.
It is impossible to retrieve duplication groups for a specific profile using this parameter.

Please confirm whether this is a bug in the implementation or a documentation mismatch.
