Atlassian Connect Express - Error on startup

[ClemensJ]

I am trying to get a first ACE plugin running. After the following sequence of commands I can only get an error during startup. What am I doing wrong?

1. atlas-connect new my-plugin
2. npm install
3. Edit credentials.json to my cloud Confluence instance
4. npm start

Error is:

> node app.js

nvm is running node lts/argon @4.8.3

What is ticking me off is, that I am trying to register in a Confluence instance and register-jira-conf.js is throwing the error.

I am not sure how it was actually connected but installing the needed build tooling for npm and 'npm install'ing freshly solved the problem.

Build tooling can be installed with 'npm install --global --production windows-build-tools'
