Starter App does not start - UnhandledPromiseRejectionWarning

[Daniel38154]

I have issues with your LinkedIn Learning Lab "Create a base box, part 1" which so far taught me quite a few things.

The proposed change by Wolfang fixes the issue.

If I modify install-ngx.sh to
sudo npm install -g generator-ngx-rocket@6.2.1 the error goes away and I can access the starter app.

Without specifying a version in install-ngx.sh generator-ngx-version is installed at version 7.1.0 at the time of writing.

This the output of the initial vagrant up run around the error:
