ElasticSearchClientServiceImpl 1.22.0 x Elastic Search 7.17.9 - Charset Issue

[#1]

Hi Everyone,

I'm having an issue while connecting to ES 7.17 with ElasticSearchClientServiceImpl 1.22.0 which seems to be a bug in the Rest Client.

This is my configuration :

This is the error :

This is what pops up in the bulletin board :

I have verified connection to ES via postman and it works fine &  i have single node for ES and Nifi is also in a single node mode

Any suggestions?

Thanks
