Logstash sync mongo data to elasticsearch - elasticsearch

Question

I'm newbie for using Logstash and Elasticsearch. I wanted to sync my MongoDB data into Elasticsearch using Logstash Plugin (logstash-input-mongodb).
In my mongodata.conf is
input {
uri => 'mongodb://127.0.0.1:27017/final?ssl=true'
placeholder_db_dir => '/opt/logstash-mongodb/'
placeholder_db_name => 'logstash_sqlite.db'
collection => 'twitter_stream'
batch_size => 5000
}
filter {
}
output {
stdout {
codec => rubydebug
}
elasticsearch {
action => "index"
index => "twitter_stream"
hosts => ["localhost:9200"]
}
}
While I running bin/logstash -f /etc/logstash/conf.d/mongodata.conf --path.settings /etc/logstash/
The error was displayed like this
Sending Logstash logs to /var/log/logstash which is now configured via log4j2.properties

Please help me, I don't have any idea about this.

Your configuration is wrong, you need to specify what type of input you are using.
Try to change your input to this one:
input {
mongodb {
uri => 'mongodb://127.0.0.1:27017/final?ssl=true'
placeholder_db_dir => '/opt/logstash-mongodb/'
placeholder_db_name => 'logstash_sqlite.db'
collection => 'twitter_stream'
batch_size => 5000
}
}
