Elastic Stack Elasticsearch

I have debug and tested from ColdFusion and Postman both are giving me same response.seems that fscrawler not taking passed index name.

ColdFusion log:

"Information","ajp-bio-8014-exec-9","12/20/19","09:55:09",,"Starting HTTP request {URL='http://172.16.110.74:7777/fscrawler/_upload?debug=true', method='POST'}"
"Information","ajp-bio-8014-exec-9","12/20/19","09:55:13",,"HTTP request completed  {Status Code=200 ,Time taken=3486 ms}"

PostMan log
