Coldfusion developer for Elastic Search project

We need to add elastic search in existing ecommerce to drive search, recommendations and personalization. There is a full elastic search server already setup with a few datafeeds and schemas (products, categories ,locations). The website is made using Coldfusion and vue.js. I exported the data in json format for importing into elasticsearch. Created an index for wj-product in kabana index pattern for importing the csv data from mysql into elastic. Right now I'm facing some issues during import process. Need a developer with expertise in Elasticsearch and Coldfusion.
