Could you please report an <http kotl in issue|issue> with some steps to reproduce

Jilles van Gurp · Answer

I have no way to reproduce this other than setting k2 to true on this project

dmitriy.novozhilov · Answer

Is this project is open source by any chance

Jilles van Gurp · Answer

no it s our main app Pretty large code base and no hint of which part of it is the problem

Jilles van Gurp · Answer

I ll file a bug for the stack trace of course Looks like something that shouldn t be happening in any case

Jilles van Gurp · Answer

Jilles van Gurp · Answer

Tracked down some more detail with < dmitriy novozhilov> It looks like having properties of type dynamic in data classes is triggering this This is one of the offending classes ```data class Event val type String val target dynamic val sourceTarget dynamic val propagatedFrom dynamic val layer dynamic ```
