Logstash not able to load mongodb output plugin

[gauravaradhye]

I am getting following error with logstash 6.2.3 (also on logstash 7.7.1) while using mongodb output plugin. I am running logstash inside a container. The plugin is installed without any problem and I can also list it, but it fails to load. Is there any known reason/fix available for this issue?

Couldn't find any output plugin named 'mongodb'. Are you sure this is correct?

Do you have the MongoDB jdbc drivers in the same classpath?
