Error Whitelabel Error Page: There was an unexpected error (type = Not Found, status = 404) when querying with mapping over level 1 Faced an extremely ambiguous and incomprehensible problem in my opinion. I have an application on Spring Boot + Kotlin. Previously, the application had exceptions for Rest controllers; recently there was a need to give html in responses, and therefore added a regular controller. However, when mapping this controller to more than 1 level - all requests (with more than 1 level) cause an error: Whitelabel Error Page This application has no explicit mapping for / error, so you are seeing...

Kotlin call overloaded function by parameter type (when only interface type is known) Our codebase has an interface with a large number of implementations. These are serialized, stored, and deserialized. When one is deserialized, we call a function that takes the interface type, which then has a giant when clause that branches based on the specific type, i.e. when (t) { is SubType1 -> ... is SubType2 -> ... is SubType44 -> ... } This is gross and adds high complexity to the function. One possibility is to move the action that we want to perform to...

Kotlin runtime error kotlin.Any is not found I have a multi-module project. With the same build, the apk's size may differ by 300 kb (from 17 to 17.3 megabytes).
