Hi

I am running MySQL DB server 8.0.31 (mysql-community-server-8.0.31-1.el7.x86_64) on Red Hat Enterprise Linux Server release 7.9 (Maipo) operating system and have enabled replication between Master and Standby.

I am currently encountering the error Error_code: 1032; handler error HA_ERR_KEY_NOT_FOUND as found in mysqld.log file on Standby server.

cat mysqld.log file
