See: https://www.mongodb.com/community/forums/t/kafka-source-connector-output-schema-value-not-registering-namespace/102645/2

We took the default schema from the source connector documentation under output.schema.value and modified it as following:

• Adding namespace
• Renaming ChangeStream to MongoSourceChangeEvent

We use the schema above in output.schema.value. When the schema is registered by the connector in the schema registry - the namespace field is not included.

This creates a problem for us in Kotlin, where we can’t include namespace in the import because deserialization will fail, instead of:
import com.company.common.avro.MongoSourceChangeEvent

We are forced to remove the namespace from the schema and import it without namespace (the schema being registered is also being used to auto generate Avro classes) :
import MongoSourceChangeEvent

We want to have a proper namespace for our auto generated classes and currently this issue prevents us from doing so.
