Alright bro, here’s the deal—Microsoft.JavaScript.NodeApi.Generator isn’t playing nice when it comes to delegates inside interfaces. Basically, when you try to export an interface with [JSExport], the tool doesn’t automatically generate the marshalling code needed for those delegates. It’s a known issue, so if your code’s throwing errors, it’s not just you—it’s how the code generation works (or doesn’t work) with delegates used as parameters or return types in interface methods. Hope that helps, man! Lemme know if you need more clarity.
