LazyModuleLoader not available in lazily loaded module

advancingu commented 1 year ago

Is there an existing issue for this?

[X] I have searched the existing issues

Current behavior

Have a lazily loaded module LazyModule and a service LazyService inside it that itself wants to use LazyModuleLoader to load further modules.

Running an application like this fails with an error:

Error: Nest can't resolve dependencies of the LazyService (?). Please make sure that the argument LazyModuleLoader at index [0] is available in the LazyModule context.

Minimum reproduction code

https://stackblitz.com/edit/nestjs-typescript-starter-1eknf8?file=src/app.module.ts

Steps to reproduce

Run the reproduction code.
See error message in console.

Expected behavior

LazyModuleLoader should be usable in services of modules that were lazy loaded.

Looks like we can't inject LazyModuleLoader in lazy-loaded providers. Not sure if this is the intended behavior tho.
