'Generating Deployment Script' step consistently failing during Zip Push Deploy - applicationinsights node module exception

[NathanBlaise-MSFT]

Repro steps.

Our project consistently builds on our local dev machine, and even when we attempt to deploy a zip file that was previously deployed successfully (and currently running in the deployed build), this error still reproduces.

We usually use Zip Push Deploy via the Kudu API, but have also attempted using the Kudu UI and encountered the same issue.
The issue still reproduces after starting the web app.

The log/error given by the failure.

After the deployment step 'Generating Deployment Script' we get the following error:

I was able to deploy by disabling Application Insights on the Web App. While this is a workaround for now it seems there's a bug in the NodeApplicationInsightsAgent Site Extension being used by the kuduscript.cmd to generate the deployment script.
