Ok, the `NoClassDefFound` can sometimes be caused by a driver version mismatch or an invalid path, so I would double check the version and folder location [as per this thread](https://discuss.elastic.co/t/logstash-and-mongodb-input/297535).

Otherwise, depending on the version of Elasticsearch you are looking to ingest into I can think of a couple of other options:

1. There is a beta of the [MongoDB client connector that can be used with Python available as of 8.4](https://www.elastic.co/guide/en/enterprise-search/current/build-connector.html) that you could leverage which is available on the free tier.
2. Do you have a license for Elastic at all and running 8.5 or later? Another option would be to take a look at the [MongoDB native connector](https://www.elastic.co/guide/en/enterprise-search/current/mongodb-start.html), but it is a feature available for platinum license and above.
3. [Exec input plugin](https://www.elastic.co/guide/en/logstash/current/plugins-inputs-exec.html) which is discussed in [this old thread](https://discuss.elastic.co/t/logstash-and-mongodb-input/297535).

Do let us know how you get on!
