I have an operation accepting a list of objects which use inheritance in the request body. When executing a test, I get the following error:

io.micronaut.http.client.exceptions.HttpClientResponseException: 
Error decoding HTTP response body: Error decoding stream for type [interface java.util.List]: Missing type id when trying to resolve subtype of [simple type, ModelVO]: missing type id property 'type'
 at [Source: (byte[])"[{"enabled":true, ...}]"; line: 1, column: 168] (through reference chain: java.util.ArrayList[0])
	at io.micronaut.http.client.netty.DefaultHttpClient$12.channelRead0(DefaultHttpClient.java:2186)
...

Caused by: com.fasterxml.jackson.databind.exc.InvalidTypeIdException: Missing type id when trying to resolve subtype of [simple type, class ModelVO]: missing type id property 'type'

	at com.fasterxml.jackson.databind.exc.InvalidTypeIdException.from(InvalidTypeIdException.java:43)

If I change the operation to just take one object instead of a list of those objects it works perfectly.

After debugging for a while I assume it's just the test client not serializing the discriminator property as expected. I have created a test case covering this issue: github.com/BrandonSchmitt/micronaut-openapi-codegen@04b7cc6a4e
