Binlog events are not getting emitted in mysql RDS version:5.6.41

Hi, I have a mysql RDS replica instance which is configured properly, I am able to do a
SHOW BINARY LOGS and the binlog format is set to ROW. When try to use and get the events in debug mode. The last event I am getting is this
--> ComBinlog {
command: 18,
position: 4,
flags: 0,
serverId: 650931968,
filename: 'mysql-bin-changelog.144390' }
Not getting even the bin log ROTATE event even though i see new binlog files getting emitted. Am I missing any configuration or something on the RDS instance?

Update: Found out that binlog events are flowing only when binlog_checksum is set to crc32 in the parameter group attached to the RDS instance.

@ramaguruprakash may I ask what is the previous value of binlog_checksum before crc32? thanks
