Hi everyone,

I'm having trouble creating a record with DX API using a savable data page. The API call is successful only if the payload contains just the key field of the data type. If I specify any other field, the call fails with the following response:

Code	Details
422	Error:
Response body
Download
{
  "errorClassification": "Validation fail",
  "localizedValue": "Validation failed.",
  "errorDetails": [
    {
      "message": "ERROR_INVALID_REQUEST_PAYLOAD",
      "erroneousInputOutputFieldInPage": "",
      "erroneousInputOutputIdentifier": "",
      "errorClassification": "",
      "localizedValue": "Invalid request payload",
      "messageParameters": []
    }
  ]
}

In the logs, I see the following:

For D_apitestdatatypeSavable, the field fieldB wasn't found in the view Create for the flow action CREATE 
Fields are invalid for the data view 'D_apitestdatatypeSavable' - action 'CREATE' 
Invalid request payload 

I have a data type with ID MyOrg-Siqdemos-Data-ApiTestDataType, it contains two text fields, fieldA and fieldB. I generated the data pages on the Sources tab of the data type. The key of the type is fieldA. The ID of the savable data page is D_apitestdatatypeSavable.

The REST operation is POST /data/{data_view_ID} Create data record. The request body is:

{
  "data": {
    "fieldA": "foo1",
    "fieldB": "bar1"
  }
}

The question is, what am I doing wrong?
