I swear to god, sometimes I really don't know what Typescript really wants from me. It's like some old god: you know it needs a sacrifice but the god is not telling you exactly what he wants. So you can only try and pray.
Yeah I don't get why it spits out whole types instead of only differences between them. Like "function expects non-null 'some.param.in.object' of type 'string' in argument 'someArgument', which is missing in passed argument".
