Expected behavior

I expect the tests to run in all 3 modes.

Actual behavior

Jest fails to parse the configuration properly and crashes.

Additional context

Using latest node js LTS. (22.18)

Hello, same issue with cjs config and Node.js >= 22.18.0

I filed this bug because I could not get jest-preset-angular to work in my own setup and hoped that getting this example fixed could show me how to do it right. I think it's a wider problem than just a documentation issue. Please prioritize.
