I have a traditional app. I would like to use the Constellation DX API for adding data records to one of my data objects as described here: https://docs.pega.com/bundle/dx-api/page/platform/dx-api/endpoint-post-data-data-view-id.html

I realize this won't work without an Rule-UI-View - but I cannot create them without migrating my app or enabling hybrid mode. So I tried creating views (Create and pyEdit) from scratch, but to no avail.

HTTP calls to {{baseUrl}}/data/:data_view_ID calls still give me an error message:

{
    "errorClassification": "Validation fail",
    "localizedValue": "Validation failed.",
    "errorDetails": [
        {
            "message": "ERROR_MISSING_DATA_RECORD",
            "erroneousInputOutputFieldInPage": "",
            "erroneousInputOutputIdentifier": "",
            "errorClassification": "",
            "localizedValue": "Data Record is missing",
            "messageParameters": []
        }
    ]
}

Any idea how to work around that? All I need is the ability to add and query records for data objects.
