Question
Unable to read binary log and warning messaged displayed to re-sync the connector.
Environment

1. As per the connector setup documentation, set the binary log retention period to a value between 24 and 168 hours using the following command (168 is set in the command):
CALL mysql.rds_set_configuration('binlog retention hours', 168);
2. Re-sync the connector to sync any missed updates.
