Would you mind posting a screenshot of the error?
I hope that you have resolved this issue - if not please copy the output of the command and I can take a look.
Another option is Dremio, a new open source project for connecting Elasticsearch and other data sources to Tableau. Dremio gives you full SQL access, and provides tight integration with Tableau.

Dremio works with other data sources too, like MongoDB, Hadoop, Amazon S3, relational databases, and more.
Give it a shot, and good luck!
