What is the correct way to make Nuxeo work with MongoDB and Elasticsearch?

[Belgacem_Ghilou]

Hello everyone, I just configured Nuxeo (LTS 2019) to work with Elasticsearch (6.5.3) and MongoDB (3.6.8), Nuxeo works fine with these two servers now, but every time Nuxeo starts, I found these logs in the server.log file :

======================================================================

And when, I do “reindex elasticsearch” via Nuxeo Dev Tools, I end up with the following logs in the “server.log” file:
