Angular 18 Standalone: "Pipe is Undefined" Error When Using RxJS Pipe in NgRx Effects

Problem:

When I try to use pipe in the createEffect method, I get an error saying that pipe is undefined. This is confusing because pipe works perfectly in other parts of my project, such as within my services. What I’ve Tried:

Verified all NgRx and RxJS imports in UsersDataEffects.
Cleared the cache and reinstalled node_modules.
Confirmed that provideEffects is properly configured in main.ts.
Checked Actions to ensure it’s injected correctly (the subscribe in the constructor works as expected).


Question:

Why am I getting an "undefined" error when using pipe in NgRx effects within an Angular 18 standalone setup? Is there something specific about Angular 18’s standalone or NgRx configuration that might cause this? Any insights would be appreciated!
