GitLab Issue: https://lab.civicrm.org/dev/core/issues/296

Before

{
   "is_error": 1,
    "error_message": "'name' specified in OR group but not added to params"
}

After

    {
    "is_error": 0,
    "version": 3,
    "count": 2,
    "values": [
        {
            "entity_id": "203",
            "latest": "Edu",
            "id": "1",
            "0": "Edu"
        },
        {
            "entity_id": "203",
            "latest": "S",
            "id": "2",
            "0": "S"
        }
    ]
}

Has unit tests for variants of return definitions: array, comma-separated and list of return parameters.

Technical

Unit test testGetCustomValueReturnMultipleApiExplorer fails without 55000cc.
