I try to collect CloudFront data by splunk-logging function on Lambda .
It seems AWS can not recognize parameter of "Environment variables" like below screenshot.

Hence I change some code on "splunk-logging" and work.
But we need check and modify appropriate code.

What I've changing below.
- Use HEC URL & token instead of "Environment variables"
const SPLUNK_HEC_URL = "https://SPLUNK FQDN/services/collector/event";
const SPLUNK_HEC_TOKEN = "SPLUNK HEC TOKEN";
- To get response
const response = event.Records[0].cf.response;
callback(null, response);
