Facing logstash compatibility issues

Question

I am trying to move data from AWS ElasticSearch 1.5 to AWS OpenSearch 2.11 with the help of logstash. I have downloaded the logstash from here :

https://artifacts.elastic.co/downloads/logstash/logstash-oss-7.16.3-x86_64.rpm

Further, I am using the below conf file :

input {
    elasticsearch {
        hosts => "https://search-es15domain-blog.us-east-1.es.amazonaws.com:443"
        index => "index-28-feb"
    }
}
 
 
output {
    opensearch {
        hosts       => "https://search-os211domain-blog.us-east-1.es.amazonaws.com:443"
        index       => "logstash-28-feb"
        ecs_compatibility => disabled
        ssl_certificate_verification => false
    }
}

When running logstash it is returning and failing with the following logs :
