onMissing option doesn't work with nested objects

[trevore-q4]

I have an object like:

class Metadata {
  @attribute()
  valueA?: string;

  @attribute()
  valueB?: string;
}

@table("documents")
class Document {
  @hashKey()
  key: string;

  @attribute({ memberType: embed(Metadata) })
  metadata: Metadata;
}

Using DataMapper.update with the onMissing option set to skip, if I try to update a single property in the nested object, all missing properties are removed, not skipped as the option would suggest.

Sample code:

const doc = new Document();
doc.key = "<hashKey>";
doc.metadata = new Metadata();
doc.metadata.valueB = "new value";
const dataMapper = new DataMapper();
dataMapper.update(doc, { onMissing: 'skip' });

Result is that valueA gets stripped from the document.

I have the same problem. This is pretty much a show stopper for me. I need to be able to patch nested objects.

Same issue here. ORM that does not update an entire record must fix
