Error creating kafka sink connector, How to create a connector using timestamp mode?

Question

I am building kafka using AWS MSK service. I am trying to copy data from source DB to target DB data. The cluster has been created. And the source connector is also created, but an error occurs when creating the sink connector.

1. org.apache.kafka.connect.errors.ConnectException: Tolerance exceeded in error handler
2. Caused by: org.apache.kafka.connect.errors.DataException: Only Struct objects supported for [converting timestamp formats], found: java.lang.String

*If I give the option "errors.tolerance=all" in the sink connector config, the connector is created normally, but no data is entered in the targetDB.

[source connector config]

connector.class=io.confluent.connect.jdbc.JdbcSourceConnector
timestamp.column.name=DATE
