Hello In my custom rest tap I want extract only fields that I need, but it doesn’t work with nested objects In my schema definition I have

th.Property(
    "car_info",
    th.ObjectType(
        th.Property("mark", th.StringType),
        th.Property("model", th.StringType)
    )
),

but I get

{"car_info": {"body_type": "ALLROAD_5_DOORS", "engine_type": "DIESEL",  "mark": "PORSCHE", "model": "CAYENNE"}}

How can I skip fields that I don’t need?

In the SDK, fields that are undefined by your schema will generally be removed by default - so you might not need to do anything more than you've done already. The user may see a log message that the undefined properties were ignored. To be more explicit, you can optionally use

post_process()

to remove or "pop" the properties you don't want to pass on.

Ignoring doesn’t work with nested properties Thanks, I’ll try post_process()

Yes, that's right. Gotcha. Then yes, post_process() would be the best bet 👍
