Exception in JDBC sink connector

Hi matriv

After adding postgresql-42.7.3.jar it throws the below exception

Caused by: org.apache.kafka.connect.errors.ConnectException: Sink connector ‘cratedb-connector’ is configured with ‘delete.enabled=false’ and ‘pk.mode=kafka’ and therefore requires records with a non-null Struct value and non-null Struct schema, but found record at (topic=‘Mytopic’,partition=0,offset=20,timestamp=1722577031564) with a HashMap value and null value schema.
