[@nx/express 18.0.4] nx g applications or libs throws error

[nawlbergs]

Current Behavior

Both the Nx UI plugin and command line throw a Cannot read properties of undefined (reading 'test') error. No matter what options/flag are set.

This is in a brand-new nx repo... I added nx... then I added an @nx/angular app... the @nx/express app will not generate.

Expected Behavior

An express app to generate... or even a dry-run print out when using the UI.

Steps to Reproduce

1. Create a new app with nx init. Try to add an @nx/express application.

After more farting around with this... it seems I cannot add a second library or application period!

If I:

1. Revert back to my initial commit... (which is basically just an empty repo with an nx.json file)
2. Added a js/lib using the NX UI.
3. Try to do it again for a second library nx g @nx/js:library --name=lib2 --unitTestRunner=jest --projectNameAndRootFormat=as-provided --no-interactive --dry-run
4. I get the same error:

nx g @nx/js:library --name=lib2 --unitTestRunner=jest --projectNameAndRootFormat=as-provided --no-interactive --dry-run

>  NX  Generating @nx/js:library


 >  NX   Cannot read properties of undefined (reading 'test')

   Pass --verbose to see the stacktrace.
