Nullable return type causes hides network errors

[OSemenovBoyarka]

Ktorfit version

2.0.0

What happened and how can we reproduce this issue?

I had some Ktofit service interfaces with nullable return types, e.g.:

@GET("some/path")
suspend fun getSomeData(): SomeDataType?

In case I have network error for such requests - function just returns null and not throw any errors.

What did you expect to happen?

If a request encountered network error - I expect exception to be thrown. And I expect function to return null in case backend returned empty response body.

In case this is an intended behavior - I think it should be documented.

Is there anything else we need to know about?
