Yarn 2.0 - No provider for [object Object]!

I'm suddenly having the following error, even though I'm not doing any Dependency Injection yet. All classes that I'm importing into my resolvers are already pre-injected.

Also tried to JSON.stringify the exception error on Apollo Server Plugins, but without success.
