Hello 👋🏽

I’ve gotta a question here which I’m not entirely sure if it relates with Coroutines or Ktor. Apologies if this is the wrong channel.

Well, I’ve recently updated Kotlin  1.4.10 -> 1.4.32 and Ktor 1.4.2 -> 1.5.3 . I was definitely expecting some of Unit tests to break due to compatibility and I’ve already fixed them. However, there are still 4 of them that I’m struggling to understand what could be wrong.

When one of the unit tests starts, it adds an entity to a Global Variable with type mutableListOf<MyModel>(). I can confirm that the value was added successfully.  ArrayList@XXXX. However, when one of the routes of my Ktor server attempt to read the value from that Global Variable, it is empty and the id of the object is now ArrayList@YYYY. It looks like when embeddedServer(…).start() is executed, it creates a new instance of the Global Object, hence it is empty.

I’ve already tried many things, SynchronizeListOf, add the global variable into an object, but no matter what I do the reference of the GlobalObject into Ktor is always different.

Would anyone be able to shed some light, please?

Thanks heaps.
