Transfer httpenpoinds metrics using http module-metricbeat - elasticsearch

Question

In order to ship the metrics endpoints (/metric) of my spring-boot app ,I used http module in metricbeat , I'm following the official doc in elastic.io website to install and configure metricbeat, but unfrontenly, the transport of metrics was incorrect although the connection had been established.
.I changed fields.yml file to create a specific template for http module only
fields.yml
- key: http

Previously, I used httpbeat and everything was great,the name of fields in elasticsearch index are compatible ... , since I've moved to use http module everything had been changed ,I'm using it to get a predefined dashboards in kibana .
Any help please ?
