while running

bin/pulsar-admin sinks localrun --sink-config-file <<path-to-config.yaml>

I faced this :

ERROR org.apache.pulsar.functions.LocalRunner - Encountered error starting localrunner

`java.lang.IllegalArgumentException: Could not validate sink config: Cannot construct instance of

<http://org.apache.pulsar.ecosystem.io|org.apache.pulsar.ecosystem.io>.lakehouse.SinkConnectorConfig

(no Creators, like default constructor, exist): abstract types either need to be mapped to concrete types, have custom deserializer, or contain additional type information`
