Welcome!

Are you using spring by any chance?

I am using enterprise java beans with weblogic

Are you using the transport client or the rest client? You should use the rest client.

I am using x-pack-transport I am quite new in Elastic search. Actually I just upgraded from 7.6.2 version . We cannot switch to rest client right now. Is there any possibility to solve this in this manner?

What is your full pom.xml? Could your reproduce the problem with a sample project?
