Mirror maker2 connector graceful stop error

I configured MirrorMaker2 (3.0.0) on kubernetes cluster to replicate data from one AWS MSK cluster to another. Topics, messages and offsets replication is working but there is an error message coming frequently

file:Worker.java method:awaitStopTask line_number:860 
   thread_name:DistributedHerder-connect-7-1 @version:1 
   logger_name:org.apache.kafka.connect.runtime.Worker message:Graceful stop of task.    
   MirrorCheckpointConnector-2 failed. class:org.apache.kafka.connect.runtime.Worker

Is it false-positive which can be ignored or need to be fixed?
