Library compiling error with JObject type of argument

[Mikou78 (Mikko Hakala)]

Hi,

I tried to create Library that includes workflow with Newtonsoft.Json.Linq.JObject type of argument. When I try to publish that Library, there comes compiling error (sorry about finnish language, but “kohteessa” means used file/class/etc.);

Unexpected error has occured during the library compilation process:
System.ArgumentException: Object of type ‘System.Activities.InArgument1[Newtonsoft.Json.Linq.JObject]' cannot be converted to type 'System.Activities.InArgument1[Newtonsoft.Json.Linq.JObject]’.

Anyone has noticed same or does UiPath has something to comment about this issue?

Problem was related to my custom NuGet package which included custom DLL but also Newtonsoft DLL. I removed Newtonsoft DLL from NuGet package and now compiling works.
