I think this is lacking some documentation, and I don’t know if it’s the intended effect, but-
If I add a new field with a default value to an existing Model, and then I retrieve this new field for a conditional save, the new field is actually populated with null instead of the default value, causing the conditional save to fail.

However, if you try to fetch the value via Pynamo, such as Model.new_field, this returns the expected default value. This seems super misleading.
