Hi @paulsmithkc this is actually a bug in the applicationinsights npm module introduced in v2.4.0. I recommend you downgrade the npm package to v2.3.6 as a workaround and track microsoft/ApplicationInsights-node.js#1063 for further updates

Closing as the applicationinsights package released v2.4.1 a few days ago to address this bug
