Getting An unknown error occurred sending a bulk request to Elasticsearch

Elastic Stack Logstash
1

After Starting the logstash the logs are fetching for 5 mins after that in logstash facing below error :
An unknown error occurred sending a bulk request to Elasticsearch (will retry indefinitely) {:message=> "incompatible encoding: IBM437 and UTF-8", : exception=>Encoding:: CompatibilityError

If we again restart the logstash again facing same issue after 5 mins.

logstash has decided that your events are encoded as IBM437 and elasticsearch does not like that. You may be able to fix this by telling your input what encoding it should be using.
