Platform: Effects in Angular library not receiving injected actions on prod build (aot=true)

[l3ender]

Minimal reproduction of the bug/regression with instructions:

Clone https://github.com/l3ender/ngrx-aot. Running app without AOT works (npm run start). Running with AOT (npm run start:prod) causes bootstrap to fail. It appears that items (action and service) are not injected into the Effect.

Firefox error:

TypeError: this.actions$ is undefined

Chrome error:

Uncaught TypeError: Cannot read property 'pipe' of undefined

Expected behavior:

App behavior would be the same with or without AOT.

Versions of NgRx, Angular, Node, affected browser(s) and operating system(s):

   "@angular/core": "^7.1.3",
    "@ngrx/effects": "^7.0.0",
    "@ngrx/store": "^7.0.0",

Using same version of Angular CLI (7.1.3).

I would be willing to submit a PR to fix this issue

I'm not sure where I'd begin.

The problem was caused by a barrel import, https://github.com/l3ender/ngrx-aot/pull/1 contains a fix.

[aleksandar-petrovic]

This problem occurs in my project.
I tried updating project to angular 8 and ngrx to 8 but it didn't help, it is the same, actions are not injected in service
Any advice?

@aleksandar-petrovic Having the same problem here, did you manage to get it working?

[aleksandar-petrovic]

Yes I did.
I had index.ts which was exporting Effects from effects.ts file. And then used that export as import in Effects.forFeature
After changing to direct import without index.ts it worked.

@aleksandar-petrovic Thanks! That fixed it for me.
