NG0912: Component ID generation collision detected

[robmanganelly]

I opened this issue as a question because I cannot blame nx for it, as I don't have the evidence, even though there are other similar issues here. See #19198

I can't find enough information about the real cause of it to make proper debugging.

Project setup:

• primeng
• angular 19.0
• nx
• analogjs plugins to enable vitest (as provided by nx, no extra config)

NG0912: Component ID generation collision detected. Components 'BaseIcon' and 'BaseIcon' with selector 'ng-component' generated the same component ID. To fix this, you can change the selector of one of those components or add an extra host attribute to force a different ID. Find more at https://angular.dev/errors/NG0912
NG0912

This only happens when I try to test ( nx foo:test ) an app or lib on my monorepo that contains components.
primeng usually requires some providers when working on the app, but in this case I have not provided anything, as my unit testing focuses on component class (methods and props)
