Elastic Search integration with Magneto 2.3.3

I have tried to use and configure the Elastic search feature. I have installed the below packages and respective versions,

Java - 11.0.7

Magento 2.3.3

Elastic search: 6.8.8

Module installed from git branch is: 2.8.x

All packages, configurations are done and necessary plugins are installed. but always getting this error in the frontend while searching.

Exception #0 (LogicException): catalog_product index does not exist yet. Make sure everything is reindexed.

I have tried in many fixes but it's not working. Please help me to solve this issue.

Welcome!

There is nothing we can do here as the error does not seem related to Elasticsearch but to Magento or the Magento connector. I'd ask Magento project for help IMO.

Thank you David for your promptly response.
