While using JDBC stages pipelines are failing with following error:-

JDBC_06 - Failed to initialize connection pool: com.zaxxer.hikari.pool.HikariPool$PoolInitializationException: Failed to initialize pool: Communications link failure

Caused by: javax.net.ssl.SSLHandshakeException: No appropriate protocol (protocol is disabled or cipher suites are inappropriate)

add ?enabledTLSProtocols=TLSv1.2 in the JDBC URL.
