Socket error while from 127.0.0.1 while installing Splunk HTTP Event Collector logging interface for JavaScript

[msilva]

Hi,

For our AWS lambda services, we will need to send events to a Splunk Cloud instance. While installing Splunk HTTP Event Collector logging interface for JavaScript (https://github.com/splunk/splunk-javascript-logging), we got this error: 

npm install --save splunk-logging

I assume Splunk Cloud is supported?

Requirements

• Node.js v4 or later. Splunk logging for Javascript is tested with Node.js v10.0 and v14.0.
• Splunk Enterprise 6.3.0 or later, or Splunk Cloud. Splunk logging for Javascript is tested with Splunk Enterprise 8.0 and 8.2.0.
• An HTTP Event Collector token from your Splunk Enterprise server.

Could you please investigate this issue? Why is there a connection to 127.0.0.1:4873?

Kind regards,

Moacir
