ng generate: An unhandled exception occurred: The "path" argument must be of type string. Received undefined

When I run ng g foo or ng g library foo, I get

An unhandled exception occurred: The "path" argument must be of type string. Received undefined

My log has,

For me this was because I had a specific unrelated project in my angular.json that lacked

"projects": {
  "demo-app": {
    "projectType": "application"
  },
}

This could be fixed by either deleting the entry for demo-app or adding the root entry,

"projects": {
  "demo-app": {
    "projectType": "application"
    "root": "projects/demo-app"
  },
}

I've opened up issue #21310 to track this
