Document.FromAttributeMap(item) all propertries empty objects

[itaikta]

I'm using IAmazonDynamoDB.QueryAsync(request) to query and filter on an index.
Now, in trying to cast the result to my model type, I'm doing the following:

var item = response.Items.First(); // I have the required checks to make sure this is valid
_logger.LogInformation(JsonSerializer.Serialize(item));

var itemAsDocument = Document.FromAttributeMap(item);
_logger.LogInformation(itemAsDocument.ToJason());

The first log comes out exactly as I would except with all the data filled in and correct.

{
  "endDate": {
          "B": null,
          "BOOL": null,
          "IsBOOLSet": false,
          "BS": null,
          "IsBSSet": false,
          "L": null,
          "IsLSet": false,
          "M": null,
          "IsMSet": false,
          "N": null,
          "NS": null,
          "IsNSSet": false,
          "NULL": null,
          "S": "2026-06-22T11:34:16.5945963+00:00",
          "SS": null,
          "IsSSSet": false
      },
      // ETC....
}

The second log shows an object with all of it's properties as empty objects:

{
    "endDate": {},
    // ETC....
}

I have spent now numerous hours searching and prompting AI for why the document serializaion isn't working propery to no avail. Any guidance would be appreciated. Thank you!

Hello, Itaikta, have you found a solution or do you need help with this topic?

Yes, I realised the fault was on me. I can't remember the specifics anymore but it was a combination of two blunders in the code. I'm still getting used to using the SDK. Thank you for checking up on me
