Can a nested class instance be passed to an entity's put method?

[dls314]

I'm calling entity.create(model).go() where the model is a class instance and has properties that are also class instances modeled in the entity's schema as map attributes.

I think this doesn't really work because of
https://github.com/tywalch/electrodb/blob/master/src/schema.js#L44

My outcome is that I get an error message like

ElectroError: Invalid value type at entity path: "event". Expected value to be an object to fulfill attribute type "map" - For more detail on this error reference: https://electrodb.dev/en/reference/errors/#invalid-attribute

Is this what I should expect to see if I'm using a class instance or nested class instance and not simply plain objects?
