Circular dependency on SSR/Angular Universal

[cskiwi]

Hi,

I'm trying to figure out why I'm getting a Circular dependency, this only happens when I run the project for the SSR.
if it runs on client side, I have no error's. So this must be something specific to the angular universal rendering.

But I can't figure out what I have to change to make it work.
maybe it's something totally different that eventually gives this error)

If anyone can help me, I would be very happy.

the graphql module (this get's only imported once, in the AppModule)

Could you solve the issue? I'm having this same problem when the SSR is activated :(

@danidan2905 this was while ago, but I think I solved it via using the something: Relation<Foo> instead of something: Foo in all your classes
