stack overflow when compiling app

[pehrlich-arbor]

Is there an existing issue for this?

• I have searched the existing issues

Current behavior

When booting the app with the given test module setup, I get a stack overflow. Not sure what's causing it.

Originally I was troubleshooting an issue which occurred sometimes when some a service's constructor throws an error, this would occur. While thinning down the app, this may be that issue is obscured by whatever this is.

I guess there's a double ask here if possible

• Whatever the underlying issue is
• Detection of this case, and a better error message. Even if only in test this could be hugely helpful, as that's often where module DAG errors are first encountered.

Minimum reproduction code

https://github.com/pehrlich-arbor/nest-troubleshoot

Steps to reproduce

yarn
yarn jest

You can remove the error by commenting out the either forwardRef, the resolver annotation, or possibly other lines.

Expected behavior

App should boot. Instead we get a stack overflow

Other package

This test case involves a GraphQL Resolver, but I'm not sure if that's fundamental to the issue - just as far as I could narrow it down.
